Re: [xml-dev] Use xsd to specify multiple instances of existing element

Hi Ian,

I'm not sure I understand exactly what you want.  Do you want an XML schema
something like:

<xs:sequence>
    <xs:element name='Category' type='privacy'/>
    <xs:element name='Category' type='fishingType'/>
</xs:sequence>

(which would be illegal I afraid)

If not, maybe you could show us a few example XML instances.

Thanks,
