Customized Subset Document Types

["W. Eliot Kimber" <ekimber@innodata-isogen.com>]

In the architecture spec, the section "Customized subset document types 
for authoring" says:

"Customized subset document types are not compliant with the DITA 
standard, and may not be supported by standards-compliant tools."

First, change the term "compliant" to "conformant". One complies with 
regulations but conforms to standards.

At first read I didn't understand why this sentence was true.

I think it is true if the intent is that all "conforming DITA document 
types" must allow as valid all documents that use the declared modules 
and domains. Have I got this correct?

If that's the intent, then I think there needs to be a statement to that 
effect, otherwise it's not necessarily obvious why a document type that 
will otherwise only produce valid (against the doctypes as delivered) 
documents is considered to be "invalid" and the statement reads as 
something of an ad-hominem prescription.

Note too that this section and what it describes is materially different 
from the next section, which talks about renaming attributes and so on, 
which of course will result in document types that cannot be conforming 
DITA documents types, if for no other reason then they fail to satisfy 
the rules for specialization.

Cheers,

E.
