XSD question: using multiple restriction patterns

[moschen]

Hi,

I would like the content of an element to match one of two possible string patterns. How can I implement this?

Goal:
<myElement>abcd</myElement>
or
<myElement>a1b2</myElement>

Something like:

<xs:simpleType name="myElement_Type">
  <xs:restriction base="xs:string">
    <xs:choice>
    <xs:pattern value="\w\w\w\w"/>
    <xs:pattern value="\w\d\w\d"/>
    </xs:choice>
  </xs:restriction>
</xs:simpleType>

Please note, that the example is a huge simplification. In reality the pattern for each of the choices is a lot more complex.

Looking forward to receivign your comments.

Regards,Mos

Oh well, sometimes it can be so easy...It seems that this will do the trick:

<xs:simpleType name="myElement_Type">
  <xs:restriction base="xs:string">
    <xs:pattern value="\w\w\w\w"/>
    <xs:pattern value="\w\d\w\d"/>
  </xs:restriction>
</xs:simpleType>
