Redefinition of named <start>

[David Rosenborg <david.rosenborg@pantor.com>]

Hi,

 

I'm trying to figure out what the correct behaviour of the following should be:

 

A.rng:

 

<grammar>

  <start name="start">

    <element name="x">

      <optional>

        <ref name="start"/>

      </optional>

    </element>

  </start>

</grammar>

 

B.rng

 

<grammar>

  <include href="A.rng">

    <define name="start">

      <element name="y">

        <optional>

          <ref name="start"/>

        </optional>

      </element>

    </define>

  </include>

</grammar>

 

Jing rejects the instance <y><y/></y> given the B.rng grammar.

The tutorial states that a named start is just a shorthand for (given the example above)

 

<start>

  <ref name="start"/>

</start>

<define name="start">...</define>

 

So I expected the <y><y/></y> instance to be valid, but Jing wants <x><y/></x>.

 

What is the correct behavior?

 

Cheers,

 

</David>
