  The Structure Pattern is a basic architectural pattern which allows the specification of complex tabular structures which are often found in statistical data (such as Data Structure Definition, and Metadata Structure Definition). A Structure is a set of ordered lists. A pattern to underpin this tabular structure has been developed, so that commonalities between these structure definitions can be supported by common software and common syntax structures.

  There are also a number of SDMX data types which do not have these direct correspondences, often because they are composite representations or restrictions of a broader data type. These are detailed in Section 6 of the standards.
  The Representation is composed of Facets, each of which conveys characteristic information related to the definition of a value domain. Often a set of Facets are needed to convey the required semantic. For example, a sequence is defined by a minimum of two Facets: one to define the start value, and one to define the interval.
++(% style="width:981.835px" %)
++|(% style="width:107px" %)**Facet Type**|(% style="width:872px" %)**Explanation**
++|(% style="width:107px" %)isSequence|(% style="width:872px" %)The isSequence facet indicates whether the values are intended to be ordered, and it may work in combination with the interval, startValue,and endValue facet or the timeInterval, startTime, and endTime, facets. If this attribute holds a value of true, a start value or time and a numeric or time interval must be supplied. If an end value is not given, then the sequence continues indefinitely.
++|(% style="width:107px" %)interval|(% style="width:872px" %)The interval attribute specifies the permitted interval (increment) in a sequence. In order for this to be used, the isSequence attribute must have a value of true.
++|(% style="width:107px" %)startValue|(% style="width:872px" %)The startValue facet is used in conjunction with the isSequence and interval facets (which must be set in order to use this facet). This facet isused for a numeric sequence and indicates the starting point of the sequence. This value is mandatory for a numeric sequence to be expressed.
++|(% style="width:107px" %)endValue|(% style="width:872px" %)The endValue facet is used in conjunction with the isSequence and interval facets (which must be set in order to use this facet). This facet is used for a numeric sequence and indicates that ending point (if any) of the sequence.
++|(% style="width:107px" %)timeInterval|(% style="width:872px" %)The timeInterval facet indicates the permitted duration in a time sequence. In order for this to be used, the isSequence facet must have a value of true.
++|(% style="width:107px" %)startTime|(% style="width:872px" %)The startTime facet is used in conjunction with the isSequence and timeInterval facets (which must be set in order to use this facet). Thisnattribute is used for a time sequence and indicates the start time of thensequence. This value is mandatory for a time sequence to be expressed.
++|(% style="width:107px" %)endTime|(% style="width:872px" %)The endTime facet is used in conjunction with the isSequence and timeInterval facets (which must be set in order to use this facet). This facet is used for a time sequence and indicates that ending point (if any) ofnthe sequence.
++|(% style="width:107px" %)minLength|(% style="width:872px" %)The minLength facet specifies the minimum and length of the value in characters.
++|(% style="width:107px" %)maxLength|(% style="width:872px" %)The maxLength facet specifies the maximum length of the value in characters.
++|(% style="width:107px" %)minValue|(% style="width:872px" %)The minValue facet is used for inclusive and exclusive ranges, indicating what the lower bound of the range is. If this is used with an inclusive range, a valid value will be greater than or equal to the value specified here. If the inclusive and exclusive data type is not specified (e.g., this facet is used with an integer data type), the value is assumed to be inclusive.
++|(% style="width:107px" %)maxValue|(% style="width:872px" %)The maxValue facet is used for inclusive and exclusive ranges, indicating what the upper bound of the range is. If this is used with an inclusive range, a valid value will be less than or equal to the value specified here. If the inclusive and exclusive data type is not specified (e.g., this facet is used with an integer data type), the value is assumed to be inclusive.
++|(% style="width:107px" %)Decimals|(% style="width:872px" %)The decimals facet indicates the number of characters allowed after the decimal separator.
++|(% style="width:107px" %)pattern|(% style="width:872px" %)The pattern attribute holds any regular expression permitted in the implementation syntax (e.g., W3C XML Schema).
--|**Facet Type**|**Explanation**
--|isSequence|The isSequence facet indicates whether the values are intended to be ordered, and it may work in combination with the interval, startValue,and endValue facet or the timeInterval, startTime, and endTime, facets. If this attribute holds a value of true, a start value or time and a numeric or time interval must be supplied. If an end value is not given, then the sequence continues indefinitely.
--|interval|The interval attribute specifies the permitted interval (increment) in a sequence. In order for this to be used, the isSequence attribute must have a value of true.
--|startValue|The startValue facet is used in conjunction with the isSequence and interval facets (which must be set in order to use this facet). This facet isused for a numeric sequence and indicates the starting point of the sequence. This value is mandatory for a numeric sequence to be expressed.
--|endValue|The endValue facet is used in conjunction with the isSequence and interval facets (which must be set in order to use this facet). This facet is used for a numeric sequence and indicates that ending point (if any) of the sequence.
--|timeInterval|The timeInterval facet indicates the permitted duration in a time sequence. In order for this to be used, the isSequence facet must have a value of true.
--|startTime|The startTime facet is used in conjunction with the isSequence and timeInterval facets (which must be set in order to use this facet). Thisnattribute is used for a time sequence and indicates the start time of thensequence. This value is mandatory for a time sequence to be expressed.
--|endTime|The endTime facet is used in conjunction with the isSequence and timeInterval facets (which must be set in order to use this facet). This facet is used for a time sequence and indicates that ending point (if any) ofnthe sequence.
--|minLength|The minLength facet specifies the minimum and length of the value in characters.
--|maxLength|The maxLength facet specifies the maximum length of the value in characters.
--|minValue|The minValue facet is used for inclusive and exclusive ranges, indicating what the lower bound of the range is. If this is used with an inclusive range, a valid value will be greater than or equal to the value specified here. If the inclusive and exclusive data type is not specified (e.g., this facet is used with an integer data type), the value is assumed to be inclusive.
--|maxValue|The maxValue facet is used for inclusive and exclusive ranges, indicating what the upper bound of the range is. If this is used with an inclusive range, a valid value will be less than or equal to the value specified here. If the inclusive and exclusive data type is not specified (e.g., this facet is used with an integer data type), the value is assumed to be inclusive.
--|Decimals|The decimals facet indicates the number of characters allowed after the decimal separator.
--|pattern|The pattern attribute holds any regular expression permitted in the implementation syntax (e.g., W3C XML Schema).
