fixed value attributes
- Raised by:
- Paul Downey
- Opened on:
I've seen the following pattern in several vertical schemas: <xs:attribute fixed="..." /> Databindings generated from this pattern typically generate a property with the 'fixed' value assigned as a default value. No validation takes place at runtime and the application is able to assert (and therefore send) different values. I'm wondering if our advice for the fixed length of an array (ISSUE-32) applies here - that in general databinding tools don't perform validation. This seems to be also related to ISSUE-13/ISSUE-14.

2006-10-05: closed as a Basic pattern, it works with tools and allows developers to do the right thing, but in many tools doesn't populate the property with a default value or fix the value.
