This change adds an ODF font-relative first-line indent paragraph style attribute as a LibreOffice extension. The corresponding ODF standard change is tracked by OFFICE-4165. This change only implements what is minimally necessary to serialize, deserialize, and check for ODF files containing this attribute. Further changes are necessary. * Added cssLength to schema, which is equivalent to length but also allows ic and em as units. * Added loext:text-indent to schema as a paragraph style attribute. This attribute is equivalent to fo:text-indent, but accepts cssLength instead of length. * Added XML_TYPE_UNIT_MEASURE to the ODF parser, which currently accepts only the font-relative measures and forces fallback in other cases. * Added loext:text-indent to the ODF parser. This attribute accepts font-relative metrics, and will behave as an import-only alias for fo:text-indent in other cases. * Updated SvxFirstLineIndentItem to handle unit-denominated measures. * Added proof-of-concept indentation handler to Writer. This implementation is incomplete and temporary, and will be revised in future changes.

Schemas for Validating ODF Files

: draft ODF schema, with additional LO extensions
The extension schema in libreoffice/
is used by all unit tests if
--with-export-validation
is given, which is the default.
Notably this means that if you add a new feature to the ODF filters and you add the required unit test for the new feature, then most likely the test will fail with a complaint from the validator; in this case the schema needs to be updated to contain the new elements and attributes.
The extension schema uses the RelaxNG
"include
" feature to refer to the ODF
schema; this means that it only contains those parts of the schema that
actually need to be changed - this works well in many cases because the ODF
schema is quite well structured with many named patterns, but unfortunately
there are a few places where that isn't the case and large chunks needed to be
copied to override them.
In the easy case, to add an attribute you just want to search for the
corresponding element, which will have a "foo-attlist
" named pattern, and then
add another attribute like this:
<rng:define name="draw-enhanced-geometry-attlist" combine="interleave"> rng:optional <rng:attribute name="drawooo:sub-view-size"> <rng:ref name="string"/> </rng:attribute> </rng:optional> </rng:define>
Currently only the features that are actually exported in the unit tests have been added to the schema; there is still some work to do here to add everything; the crashtesting script also does ODF validation of all files and now also uses the custom schema.
Unfortunately it turned out that there are a lot of extensions already for which no proposal exists [1], and in many cases not even an entry on the Wiki [2], so clearly something like this extension schema is needed.
