By 'use', I actually meant 'define', but James's question is still
worth tackling.
James asks about specific points like content models, attribute types,
etc. -- what is the proper use of a name defined in a namespace? I'd
suggest that that's all dependent on the degree of specification.
As an example, consider the specification for elements named
{http://www.megginson.com/ns/foobar/}place. Here's one possible
example:
An element named {http://www.megginson.com/ns/foobar/}place shall
always contain the name of a geographical location.
Since I've used the verb "contain", I think that I cannot put the name
in an attribute value (since attributes are not contained in an
element):
[WRONG]
<megg:place name="Ottawa"/>
However, I've said nothing about what the name should look like or how
it should be structured, so all of the following should be conformant:
[OK]
<megg:place>Ottawa</megg:place>
[OK]
<megg:place>Ottawa, Ontario, Canada</megg:place>
[OK]
<megg:place>The city of Ottawa</megg:place>
[OK]
<megg:place>
<city>Ottawa</city>
<province>Ontario</province>
<country>Canada</country>
</megg:place>
[OK]
<megg:place>
Ottawa<br/>
Region of Ottawa-Carleton<br/>
Ontario<br/>
Canada
</megg:place>
[OK]
<megg:place>
<item>Ottawa</item>
<item>Ontario</item>
<item>Canada</item>
</megg:place>
If I want something more specific, I have to give it in the definition
(perhaps by supplying BNF or a content model, or even by specifying
the allowed structure of the character data).
All the best,
David
