Hi all,

Just working through Beginning XML (3rd Edition), and I've encountered a problem within the Schema chapter.

For those with the book for reference, I'm doing the example from Chapter 5 - Page 187.

Anyway, the example creates a schema which includes a fixed attribute declaration:
<attribute name="version" type="string" fixed="1.0"/>

In my document, I can change the version attribute to any string value without any validation issues (I'm using Toplogi Schemtron btw).

Is this expected behaviour?

I can send example files to anybody that might need them.

Thanks for looking,
Greg

Hey all (again),

I think I've resolved the issue. :)

It appears I need to select the Schema document within Topologi aswell as the xml document (although the book did specifically say I didn't need to do this!) :(

Out of interest, did anyone else encounter this problem?

Cheers,
Greg

Sounds more like a problem with your schema processor than with the example in the book. Not all schema processors implement 100% of the spec.

Thanks for the response.
