[oXygen-user] set schema on version attribute

[George Cristian Bina]

Dear Chris,

Associating a schema based on an attribute is not possible in the
current version of oXygen. We had this request a couple of time so we
will probably implement it in the future.
The equation element is not defined as a possible start element in the
DocBook schema that you use. You can create a custom version of the
schema and extend the start pattern to allow also the equation element,
like below:

<?xml version="1.0" encoding="UTF-8"?>
<grammar
  xmlns="http://relaxng.org/ns/structure/1.0"
  xmlns:a="http://relaxng.org/ns/compatibility/annotations/1.0"
  datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes">
    <include href="docbook.rng"/>
    <start combine="choice">
        <ref name="db.equation"/>
    </start>
</grammar>

Best Regards,
George
