RE: AI: Precedence order re-wording

Hi Christian, all,


------------------

1- Implicit local selection in documents (ITS local attributes on a
specific element)
 
2- Global selections in documents (using a rules element)
 	Inside each rules element the precedence order is:
 	a- Any rules inside the rules element
 	b- Any rules linked via the XLink href attribute
 
Note: If identical selections are defined in different rules elements
within  one document, the selection defined by the last takes
precedence.

Note: ITS doesn't define precedence related to rules defined or linked
based on non-ITS mechanisms (such as processing instructions for linking
rules).
 
3- Selections via defaults for data categories, see Section 6.1:
Position,  Defaults, Inheritance and Overriding of Data Categories

------------------

It look fine too me. But I'm still not sure what the right approach
should be for rules linked with non-ITS mechanism (second note above).
So far my assumption was that they would be always at the document-level
and their precedence between #2 and #3. I can see why they are useful at
that level (you assign a rule file to a document type or a set of files)
but they would be redondant if you use that within the documents
(basically conflicting with the different notations of ITS within a
document).
