XML Schema assistance

[Ray Cauchi <ray@tweek.com.au>]

Hi folks

I have defined a W3C XML Schema that allows markup of Policy documents.
(BTW - I am new at schema design!)

A valid xml structure follows:

<?xml
version="1.0" encoding="UTF-8"?>
<policy
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="myschema.xsd">

        

<section>

                

<title>Section
1
Title</title>

                

<clause>string
text</clause>

        

</section>

        

<section>

                

<title>Section
2
Title</title>

                

<clause>string
text</clause>

                

<clause>more
text</clause>

        

</section>

        

<section>

                

<title>Section
3
Title</title>

                

<clause>text
-
<link
href="http://www.website.com/">a
link</link></clause>

        

</section>
</policy>

So you can see that each main section of a document is marked up
as a <section></section>, and each section must have a
<title></title>

No problem, the schema works fine as far as I have so far
tested.

What I wish to do though, is enforce two specific <section>'s : in
other words, the first <section> in each document will always have
a specific <title>. That being, for arguments sake,
<title>Section 1: Policy Purpose</title>.

Similarly, the second section will also have a specific title - that
being <title>Section 2: Document Glossary</title>

All other <title>'s used in a document will be required (where they
exist), but their content will not be fixed.

I have made <title></title> a global element. How can i now
instantiate it twice, with specific content, once for each section?? I am
using the XML Spy schema GUI tool, and each time I try to provide a fixed
value, that value becomes global...and thus applies to all <title>
tags in the document. I am using the <title> element in the
following elements - hence its global definition :

<section>
<part>
<hmajor> (major heading)
<hminor> (minor heading)



Do I need to create a <s1title> and <s2title> separate to my
original <title> element, or is there a more clever way of
approaching this issue? I am thinking there is but I am a tad stumped!
Any assistance would be hugely appreciated.
