How to represent Selections about ids HOT 1 CLOSED

The answer was use of XSD Patterns or Facets.
For example something like this:

<ids:specification name="Human readable name for the objects; for example Grilles" necessity="required">
ids:applicability
ids:entity
ids:name
xs:restriction
<xs:pattern value="(IfcWindows|IfcDoors).*" />
</xs:restriction>
</ids:name>
</ids:entity>
</ids:applicability>
ids:requirements
<ids:property location="any">
ids:propertysetids:simpleValueExample for Stefan</ids:simpleValue></ids:propertyset>
ids:name
ids:simpleValueglazing-percentage</ids:simpleValue>
</ids:name>
ids:value
xs:restriction
<xs:pattern value="[0-9][0-9]" />
</xs:restriction>
</ids:value>
</ids:property>
</ids:requirements>

Also added the pattern that the value of the glazing-percentage needs to be 2 numbers.

from ids.
