Combine attributes (OFFICE-2241 and OFFICE-2531)

[Michael Brauer - Sun Germany - ham02 - Hamburg <Michael.Brauer@Sun.COM>]

Hi,

during the public review we received comments that the ODF schemas use 
the RNG combine attribute in a way this was not intended by the authors 
of RNG. For instance:

http://tools.oasis-open.org/issues/browse/OFFICE-2241
http://tools.oasis-open.org/issues/browse/OFFICE-2259

With the comment that belongs to OFFICE-2259, Murata Makoto contributed 
an XSLT style sheet that merges the definitions that have a combine 
attribute into a single definition, and adds a <choice> or <interleave> 
element that corresponds to the value of the combine attribute.

I have slightly enhanced this style sheet (it does now add the <choice> 
and <interleave> elements only if there are multiple definitions for a 
single name) and have applied it to the manifest and main schema. I 
would like to propose that we switch to these schema for ODF 1.2.

The style sheet itself is not very complex, so I'm very confident that 
the resulting schemas are equivalent to the original schemas. I have 
further verified that the schemas are valid RNG schemas (using the 
odftoolkit.org ODF validator implementation). As an additional check I 
have verified that the modified schema would generate the same text for 
part 1 and 3 as the original schemas.

The modified RNG schemas and the modified XSLT style sheet can be found 
in the document repository. See below.

Best regards

Michael
