How to specify existence check about ids HOT 4 CLOSED

from ids.

I've opened two new issues, since the message from Nick does not really answers my question and/or contribute to its resolval.

from ids.

Questions from Nick answered in seperate topics.
Answer on original example requiring firerating but no specific requirements to value:

		<ids:property location="any" uri="http://identifier.buildingsmart.org/uri/dummy-example/FireRating">
			<ids:propertyset>
				<ids:simpleValue>PropertySetName</ids:simpleValue>
			</ids:propertyset>
			<ids:name>
				<ids:simpleValue>FireRating</ids:simpleValue>
			</ids:name>
			<ids:value>
				<xs:restriction>
					<xs:annotation>
					<xs:documentation>The value is not of concern</xs:documentation>
					</xs:annotation>
				</xs:restriction>
			</ids:value>
		</ids:property>

Or alternatively: xs:restriction<xs:pattern value="*"/></xs:restriction> if you allow any kind of value
Or alternatively: xs:restriction<xs:minInclusive value="0" /></xs:restriction> if you want the value to be at least 0
Or alternatively many other ways are possible with the XSD Restrictions and Facets.

A technical comment: Having some value for a property is something different from having a property without a value.
The IFC schema allows such data and in some cases it makes an important difference. However, as tools do not properly differentiate it is more an academic note than a real issue.
