If this [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] 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.
	348	+|(% style="width:107px" %)interval|(% style="width:872px" %)The interval [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] specifies the permitted interval (increment) in a sequence.

This [[facet>>doc:sdmx:Glossary.Facet.WebHome]] is used for a numeric sequence and indicates that ending point (if any) of the sequence.
	351	+|(% style="width:107px" %)timeInterval|(% style="width:872px" %)The timeInterval [[facet>>doc:sdmx:Glossary.Facet.WebHome]] indicates the permitted duration in a time sequence. In order for this to be used, the isSequence [[facet>>doc:sdmx:Glossary.Facet.WebHome]] must have a value of true.
	352	+|(% style="width:107px" %)startTime|(% style="width:872px" %)The startTime [[facet>>doc:sdmx:Glossary.Facet.WebHome]] is used in conjunction with the isSequence and timeInterval [[facets>>doc:sdmx:Glossary.Facet.WebHome]] (which must be set in order to use this [[facet>>doc:sdmx:Glossary.Facet.WebHome]]).

This [[facet>>doc:sdmx:Glossary.Facet.WebHome]] is used for a time sequence and indicates that ending point (if any) ofnthe sequence.
	354	+|(% style="width:107px" %)minLength|(% style="width:872px" %)The minLength [[facet>>doc:sdmx:Glossary.Facet.WebHome]] specifies the minimum and length of the value in characters.
	355	+|(% style="width:107px" %)maxLength|(% style="width:872px" %)The maxLength [[facet>>doc:sdmx:Glossary.Facet.WebHome]] specifies the maximum length of the value in characters.
	356	+|(% style="width:107px" %)minValue|(% style="width:872px" %)The minValue [[facet>>doc:sdmx:Glossary.Facet.WebHome]] 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>>doc:sdmx:Glossary.Facet.WebHome]] is used with an integer data type), the value is assumed to be inclusive.
