I think it's probably technically allowed in the spec, but this was a limitation imposed by the GT feature type. Essentially the convention was to use the local name as the name field for the attribute types. Then since the local name is the only identifier on the AttributeType, duplicates create issues. Therefore I disabled the ability to over-ride attributes for feature types (saved alot of complexity which I did not consider worth the user cost).
Where GT featuretypes are not concerned, the parser should happily work away. Unfortunately this doesn't help you. There are some proposals and work going on for a new FT model which uses a qname structure. This would provide the necessary interface to fix this problem.

Even if the attribute is qualified in the getFeature as myns:name?Since gml:name and myns:name are in different namespaces couldn't they coexist?Or is it the unqualified declaration in describeFeatureType that isn't allowed?Thanks,Drew.-----Original Message----->From the feature.xsd file you referenced:

An abstract feature provides a set of common properties. A concrete
feature type must derive from this type and specify additional
properties in an application schema. A feature may optionally
possess an identifying attribute ('fid').
</documentation>
</annotation>
<sequence>
<element ref="gml:description" minOccurs="0"/>
<element ref="gml:name" minOccurs="0"/>
<element ref="gml:boundedBy" minOccurs="0"/>
<!-- additional properties must be specified in an application schema -->
</sequence>
<attribute name="fid" type="ID" use="optional"/>
</complexType>
GML already defines that particular element to be part of a feature ...

Hello again,
If I serve up WFS data to GeoTools with an attribute named 'name', I get the
exception below.
Is 'name' a reserved word? Am I doing something stupid again?
If I change it to anything else, ie 'namex', it works great.
Thanks for any info,
Drew.
