Thanks for taking the time to explain. So if I accept the constraint on mustUnderstand as a given, then there is no way to do what I want to do, correct? Namely, to supply any fixed or default value for this attribute?
In the general case, this would seem to be a downside of excluding the canonical representation through the use of a pattern facet. -Steve On Wed, Sep 08, 2004 at 10:40:04PM -0400, Michael Glavassevich wrote: > Hello Steve, > > Your schema appears to be invalid.
