36 36  < note the test for whether something is a specialization is to ask the question “is xxx a type of yyy” In the Cross Domain (% style="color:#e74c3c" %)Concepts(%%) the question would be “Is [[confidentiality status>>doc:sdmx:Glossary.Confidentiality - status.WebHome]] a type of [[confidentiality>>doc:sdmx:Glossary.Confidentiality.WebHome]]”. The answer is “no”. The problem here is that the cross domain (% style="color:#e74c3c" %)concepts(%%) are grouped, often in a structural and not semantic sense. This, unfortunately, is carried over in the [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] and needs to be rectified.>
