Re: XML Schema assistance

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.
