[mapguide-internals] Default values for InsertionPointX

[Kenneth Skovhede, GEOGRAF A/S]

I'm trying to fix issue #918:
http://trac.osgeo.org/mapguide/ticket/918

The ticket seems to indicate that 0.5 is the default value.
The xml fragment looks like this:

      <xs:element name="InsertionPointX" type="xs:string" minOccurs="0">
        <xs:annotation>
          <xs:documentation>X offset for the symbol specified in symbol 
space.  Does not apply to labels.</xs:documentation>
        </xs:annotation>
      </xs:element>
      <xs:element name="InsertionPointY" type="xs:double" minOccurs="0">
        <xs:annotation>
          <xs:documentation>Y offset for the symbol specified in symbol 
space.  Does not apply to labels.</xs:documentation>
        </xs:annotation>
      </xs:element>

If the InsertionPoint values are omitted, does MapGuide assume 0.5 or 0.0 ?
If it assumes 0.5 should the xsd be updated to indicate this?
