> If I change the xs:list itemType to string ({{<xs:list itemType="xs:string"
> />}}) everything works well.
> If I use other types (e.g. {{"xs:double"}}) I get an {{"Internal error -
> invalid list type"}} although the type seems to be supported (I looked at
> [BuiltinFormats.java|http://grepcode.com/file_/repo1.maven.org/maven2/org.jibx/jibx-bind/1.2.3/org/jibx/binding/model/BuiltinFormats.java/?v=source]
> - not sure if this is the right place).
> So my main issue is to get {{<xs:list itemType="xs:int" />}} working in code
> generation but I also wonder what list types are supported.
> Thanks for any help!
