Description

schema parser v2.2.0 chokes on the following lines:

<element name="_Feature" type="gml:AbstractFeatureType" abstract="true" />
<element name="_FeatureCollection" type="gml:AbstractFeatureCollectionType"
abstract="true" substitutionGroup="gml:_Feature" />

with the error message:

For '_FeatureCollection' to be a member of the substitution group set
of 'gml:_Feature', its

{abstract}

must be false.

schema parser v2.1.0 parsed this without problems.

An abstract element being in the substitutionGroup of another abstract element
is not forbidden by the schema spec.
