xsd restriction

[Ed Slen]

Hi, Guys!
Have a question about xsd restriction:

I am having an element "state" and it could be US state (Which is
easy) or Canadian postal code which is easy too (both rules are
working separately), but I am having difficulties combining this two
rules together.
Here is what I have tried:

<xsd:simpleTy pe name="StateType ">
<xsd:union>
<xsd:simpleType >
<xsd:restrictio n base="xsd:strin g">
<xsd:pattern value="[a-zA-Z]\d[a-zA-Z] \d[a-zA-Z]\d" />
</xsd:restriction >
</xsd:simpleType>
<xsd:simpleType >
<xsd:restrictio n base="b:usState ">
</xsd:restriction >
</xsd:simpleType>
</xsd:union>
</xsd:simpleType>
<xsd:simpleTy pe name="usState">
<xsd:restrictio n base="xsd:NMTOK EN">
<xsd:enumeratio n value="AL"/>
<!—and all of other states up to: à
<xsd:enumeratio n value="WY"/>
</xsd:restriction >
</xsd:simpleType>

this gives enumeration error if I use Canadian postal code.

Please, help!
What am I doing wrong?

Thanks in advance!

This works for me, assuming the prefix b is defined as your targetNamespace .

Your XML Schema snippet did not include an element declaration, I'd just check
for what might be an obvious snag:

<xsd:element name="location" type="b:StateTy pe" /> <!-- OK -->
<xsd:element name="location" type="b:usState " /> <!-- Not the Union type: Bug -->

You would get an enumeration error if the element where the Canadian postal
code appears is making reference to the b:usState type instead of the union
type, b:StateType.
