[xsd-users] C++/Parser errors from GML schemas

[Boris Kolpackov]

James,

I was test the in-development version of xsd against the GML schemas
you sent me and found out that they are not quite valid. In this version,
I decided to turn "expensive" (time and memory -wise) checks (such as
unique particle attribution, etc.) on which uncovered the whole bunch
of errors (see below). I checked one instance and turned out that the
schema is indeed invalid. For example, here is the snippet from
coordinateOperations.xsd:519:

<complexType name="OperationMethodBaseType" abstract="true">
  <complexContent>
    <restriction base="gml:DefinitionType">
      <sequence>
	<element ref="gml:metaDataProperty" minOccurs="0" maxOccurs="unbounded"/>
	<element ref="gml:methodName"/>
      </sequence>
      <attribute ref="gml:id" use="required"/>
    </restriction>
  </complexContent>
</complexType>

Now look at the base type definition (dictionary.xsd:35):

<complexType name="DefinitionType">
  <complexContent>
    <restriction base="gml:AbstractGMLType">
      <sequence>
	<element ref="gml:metaDataProperty" minOccurs="0" maxOccurs="unbounded"/>
	<element ref="gml:description" minOccurs="0"/>
	<element ref="gml:name" maxOccurs="unbounded"/>
      </sequence>
      <attribute ref="gml:id" use="required"/>
    </restriction>
  </complexContent>
</complexType>

There are two problems in this case:

 1. OperationMethodBaseType should explicitly declare each element found
    in DefinitionType (name and description are missing).

 2. We cannot add any new elements/attributes (methodName in this case)
    for valid OperationMethodBaseType content model should also be
    valid per DefinitionType.
