Now I would like to create a rule which says for example if the user chose the enumerator MY_SPECIAL_TYPE_STRING than the type of "Value" has to be "xsd:string". If the enumerator was MY_SPECIAL_TYPE_INTEGER than the type of "Value" should be "xsd:integer". And maybe if this is even possible create my own type for "Value".Better places to ask this sort of question are xmlschema-dev w3 org, xml-dev lists xml org and the comp.text.xml newsgroup. You may have to do a bit of detective work to find out how to subscribe to these.
Nice tip I will have a try.
To answer your question, you can't use XML schema to do this. (I'm not sure
even if RelaxNG can do this.)
A more schema friendly way of do this would be to do:
<xsd:complexType>
<xsd:choice>
<xsd:element name="MY_SPECIAL_TYPE_STRING" type="xsd:string"/>
<xsd:element name="MY_SPECIAL_TYPE_INTEGER" type="xsd:int"/>
<xsd:element name="MY_SPECIAL_TYPE_OF_WHATEVER" type="???"/>
</xsd:choice>
</xsd:complexType>
Your XML instance then looks like:
<MY_SPECIAL_TYPE_STRING>MyString</MY_SPECIAL_TYPE_STRING>
That's a brilliant idea. Easy to solve and I can use it right now. Thanks for your help! Best regards Stefan
