Not sure that'll work. I get a syntax error for the last line there,
but the HasNS structure blows out to:
<define name="HasNS">
<element>
<anyName>
<except>
<nsName ns=""/>
</except>
</anyName>
<zeroOrMore>
<attribute>
<anyName/>
</attribute>
</zeroOrMore>
<mixed>
<zeroOrMore>
<ref name="HasNS"/>
</zeroOrMore>
</mixed>
</element>
</define>
[sorry, I'm not great with the rnc]
which allows children to be in the parent namespace against the
fragments I'll playing with. I changed it to include the specd namespace
<define name="HasNS">
<element>
<anyName>
<except>
<nsName ns=""/>
<nsName ns="http://www.example.com"/>
</except>
</anyName>
<zeroOrMore>
<attribute>
<anyName/>
</attribute>
</zeroOrMore>
<mixed>
<zeroOrMore>
<ref name="HasNS"/>
</zeroOrMore>
</mixed>
</element>
</define>
and blew this out:
namespace local = ""
namespace ns1 = "http://www.example.com"
HasNS =
element * - (local:* | ns1:*) {
attribute * { text }*,
mixed { HasNS* }
}
which I think stops non-ns names (why I am doing this? ;) and the
specified ns on the parent. Full structures with all the other
attribute stuff attached.
