Uml Process / XML Schema profile to work seamlessly with MDG GML
« on: April 09, 2015, 01:49:02 pm »
When will the XML Schema profile work seamlessly with MDG GML?

Specifically, I want to export an application schema that includes the following unsupported or undocumented features (bugs?)
1) GML export has seemingly no support for specifying and assigning attributeGroups e.g.
      <attributeGroup name="SpatialReferenceGroup">
            <attribute name="srsName" type="anyURI"/>
            <attribute name="srsDimension" type="positiveInteger"/>
      </attributeGroup>

2) How does one include by reference i.e. <element ref="ns:myElement"/> ?
3) Is there a mechanism to include XML schema code where the above plus more fail?

Also on this topic, can XML schema in UML be defined such that I can use substitutionGroups without using <extension>?

e.g.

      <element name="AbstractQuality" abstract="true">
            <annotation>
                  <documentation>Generic quality value holder</documentation>
            </annotation>
      </element>
      <!--  -->
      <element name="GeneralQuality" type="geo:ValueType" substitutionGroup="geo:AbstractQuality">
            <annotation>
                  <documentation>Generic quality value holder</documentation>
            </annotation>
      </element>
      <!--  -->
      <element name="VCV3D" type="geo:VCV3x3Type" substitutionGroup="geo:AbstractQuality">
            <annotation>
                  <documentation>Upper triangle of a symmetric 3x3 VCV matrix defined as a list of six doubles.</documentation>
            </annotation>
      </element>
      <!--  -->
