[jira] Commented: (XMLBEANS-35) OutOfMemoryError with this schema

Body:
At first I thought this was an illegal schema (model groups can't be self referencing as per the section 3.8.6 of the XMLSchema spec), but it turns out that rule doesn't apply here. Below is a quote from a posting on xmlschema-dev:
http://lists.w3.org/Archives/Public/xmlschema-dev/2002May/0008.html
=====================
<xs:group name="error">
<xs:sequence>
...
<xs:element name="error">
<xs:complexType>
<xs:group ref="ms:error" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:group>
The circularity constraint on model groups states that the particles
of the group, at any depth, cannot include the group itself. In the
case above, the particles of the ms:error group are a sequence,
various other things, and an error element. The particles that are
part of the content type of the error element aren't particles of the
group -- as far as a validator is concerned, the element declaration
is a black box.
