[relaxng-user] Problems converting <xs:any> schema elements

[Tom Gaven]

Spencer,
   It might be good to rework the schemas manually, but as a first pass,
you might just try replacing the offending names.

Change  
<define name="any(lax:##other)5">
To
<define name="any_lax___other_5">

You'd have to be careful to keep all changes in sync, since there are
bound to be many references to this particular define.  Of course,
'anybutfoo' (or whatever name is meaningful to your schema) is more
descriptive than 'any_lax___other_5'

Let's say you have a schema like:

<xs:schema elementFormDefault="qualified" xml:lang="EN"
	xmlns:xs="http://www.w3.org/2001/XMLSchema"
	targetNamespace="foo">
	<xs:element name="example">
		<xs:complexType>
			<xs:sequence>
				<xs:any namespace="##other"
processContents="lax"/>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
</xs:schema>

The rough equivalent of the above written in the compact syntax would
be:

default namespace foo = "foo"
start = element example { anybutfoo }
anybutfoo = element * - foo { anycontents }
anycontents = mixed {
	(attribute * { text }
	| any)*
}
any = element * { anycontents }

Trang translates this to RELAX NG as:

<?xml version="1.0" encoding="UTF-8"?>
<grammar ns="foo" xmlns="http://relaxng.org/ns/structure/1.0">
   <start>
     <element name="example">
       <ref name="anybutfoo"/>
     </element>
   </start>
   <define name="anybutfoo">
     <element>
       <anyName>
         <except>
           <name>foo</name>
         </except>
       </anyName>
       <ref name="anycontents"/>
     </element>
   </define>
   <define name="anycontents">
     <mixed>
       <zeroOrMore>
         <choice>
           <attribute>
             <anyName/>
           </attribute>
           <ref name="any"/>
         </choice>
       </zeroOrMore>
     </mixed>
   </define>
   <define name="any">
     <element>
       <anyName/>
       <ref name="anycontents"/>
     </element>
   </define>
</grammar>
