Re: [PyWrapper-devel] Schema structure under TAPIR

[<m.d...@bg...>]

Milko,
pywrapper cant handle mixed content yet so you should assign it a  
simple datatype.
in your example this would be sth like this (note the extension base  
xs:string):


                 <xs:element name="Dataset" maxOccurs="unbounded">
                     <xs:complexType>
                         <xs:simpleContent>
                             <xs:extension base="xs:string">
                                 <xs:attribute name="identifier"  
type="xs:string"/>
                                 <xs:attribute name="domain"  
type="xs:string"/>
                                 <xs:attribute name="URN"  
type="xs:string"/>
                             </xs:extension>
                         </xs:simpleContent>
                     </xs:complexType>
                 </xs:element>
