[oXygen-user] XInclude and ID/IDREF validation

[Wendell Piez]

Hi,

This is a classic problem, probably with a simple solution (or 
workaround), but I can't locate it.

What can I do to get ID/IDREF to work across file boundaries when 
using XInclude to construct a document with several modules?

I have tried setting up a Validation Scenario naming the master 
document, and when subordinate modules are validated, this appears to 
be working, inasmuch as I get validation errors for all modules 
(including the master) when I validate any of them. But IDREF values 
in attributes fail validation when their corresponding ID values are 
in other modules.

I am figuring that this is either a setting I have failed to make 
correctly (where should I be looking?), or maybe a limitation of some 
kind, such as that when XInclude is involved, only attributes named 
@xml:id are respected (this is a wild guess), not just any attribute 
declared as type ID in the DTD (which is what I have).

Or maybe I will have to consider going back to external parsed 
entities? I am very reluctant to do this, since the subordinate 
documents need their own DOCTYPE declarations to pick up entity 
declarations of their own, and of course these aren't legal in 
external parsed entities.

I know this is/was a bugaboo in the specification of XInclude, but 
was figuring that in the time since its inception, solutions have emerged....

Thanks for any tips, as always.

Cheers,
Wendell
