/ "Wills, Robert" <Robert.Wills@sts.co.uk> was heard to say:
| P1. All block-level elements except the topmost ('topmost' = <article>,
| <book> etc.) have new companion elements defined with names like
| <included-XXX>, e.g. <included-section>, <included-figure> etc.
|
| P2. Grammar is changed such that wherever <XXX> is valid, <included-XXX> is
| also valid.
|
| P3. Grammar of each <included-XXX> element is defined to allow exactly one
| child element which can be either the 'real' <XXX> element or an
| <xs:include> element (or by virtue of P2 a nested <included-XXX>), e.g. in
| DTD-like-syntax:
|
| !ELEMENT included-section (section | xs:include | included-section)
| !ELEMENT included-para (para | xs:include | included-para)

I don't think that's necessary to get the "right" behavior. The trick is simply
to make sure that xi:include elements are expanded before the validator kicks
in. Then we can simply say:

   <article>
     <section>
       <title>Section 1</title>
       <para>...</para>
     </section>
     <xi:include href="section2.xml"/>
   </article>

And the validator (DTD, RELAX NG, whatever) will see

   <article>
     <section>
       <title>Section 1</title>
       <para>...</para>
     </section>
     <section>
       <title>Section 2</title>
       <para>...</para>
     </section>
   </article>

and be entirely content.

                                        Be seeing you,
                                          norm
