I agree too that it should be in a separate module.

I'm certainly no expert in XML Schema, and I may be wrong, but we should be able to use types of the XLIFF core into other modules. Complex types can be used recursively, so I don't see why they could not be used recursively across namespaces as well.

If I declare <matches> and <match> in a separate XSD module, using a reference to the source, target and originalData types declared in the core, like this:

<xs:element name="match">
  <xs:complexType>
    <xs:sequence>
      <xs:element minOccurs="1" maxOccurs="1" ref="xlf:source"/>
      <xs:element minOccurs="1" maxOccurs="1" ref="xlf:target"/>
      <xs:element minOccurs="0" maxOccurs="1" ref="xlf:originalData"/>
    </xs:sequence>
    <xs:attribute name="id" use="optional" type="xs:NMTOKEN"/>
    <xs:attribute name="origin" use="optional"/>
    <xs:attribute name="matchquality" use="optional" type="xs:integer"/>
  </xs:complexType>
</xs:element>

And in the core module do this:

<xs:element name="segment">
  <xs:complexType>
    <xs:sequence>
      <xs:element minOccurs="1" maxOccurs="1" ref="xlf:source"/>
      <xs:element minOccurs="0" maxOccurs="1" ref="xlf:target"/>
      <xs:element minOccurs="0" maxOccurs="1" ref="xlf:notes"/>
      <xs:element minOccurs="0" maxOccurs="1" ref="m:matches"/>
    </xs:sequence>
    <xs:attribute name="id" use="optional" type="xs:NMTOKEN"/>
    <xs:attribute name="translate" type="xlf:yesNo" default="yes"/>
    <xs:attribute name="approved" type="xlf:yesNo" default="no"/>
  </xs:complexType>
</xs:element>

Everything seems to be ok.

And when I have an XLIFF document like this:

<xliff version='2.0' xmlns="urn:oasis:names:tc:xliff:document:2.0"
 xmlns:m="urn:oasis:names:tc:xliff:matches:2.0"
 srcLang='en'>
<file>
<unit id='1'>
 <segment>
  <source>text</source>
  <m:matches>
   <m:match>
    <source>text</source>
    <target>target</target>
   </m:match>
  </m:matches>
 </segment>
</unit>
</file>
</xliff>
    
It seems to work fine and pass validation as well.

I've attached the three files.
Am I missing something?

Cheers,
