The XML is perfectly OK, but the schema isn't!

When you write:


                    <xs:element ref="nsSDSGeneral:PlugIn" minOccurs="0"

                    <xs:element ref="nsSDSGeneral:SDSMenuItem"
minOccurs="0" maxOccurs="unbounded"/>

                    <xs:element ref="nsSDSGeneral:PlugIn" minOccurs="0"


A schema processor can't tell if a sequence composed of only a single
"nsSDSGeneral:PlugIn" element matched the first or the second occurrence
and this type of "non determinism" is forbidden by the W3C XML Schema

1) Don't use tools that are not conform to the rec ;-) 

2) either rewrite your schema to make it deterministic or use a schema
language that doesn't require that (ie RELAX NG).

Read me on Advogato.
