[xep-support] Warning or Error on Violation of Content Model For simple-page-master

[W. Eliot Kimber]

The content model for simple-page-master is a sequence group with 
region-body first. However, the current validator does not complain if 
the order is not followed (that is, it allows the regions to be declared 
in any order).

Per recent discussion on the FO dev list, I think that this particular 
sequence group is really best modeled as an AND group, but of course the 
editors did not have that option and chose not to publish the heinous OR 
group that would be the equivalent AND group. Therefore, I think that 
XEP's validator is justified in not failing a document based on failure 
to conform to the order.

However, I think that the validator should issue a warning if the order 
is not followed as this is a technical (if harmless) violation of the 
spec and it will of course always be safest to conform to the letter of 
the spec.

Thanks,

Eliot
