To avoid of rivers and too much hyphenation, add minimum and maximum word spacing options, similar to XSL-FO/CSS and DTP software. Only limiting hyphenation was implemented: hyphenation of the words are disabled, if it's possible to expand or shrink the spaces of the line within the values specified by the maximum and minimum word spacing. First try to apply the minimum word spacing, and if not possible, then the maximum word spacing. Note: maximum allowed shrinking has been applied for the hyphenated lines instead of the minimum to remove the hyphenation, yet. With the suggested default word spacing values, this results no or minimal differences. New UNO paragraph properties: com::sun:⭐:text::ParaWordSpacingMinimum com::sun:⭐:text::ParaWordSpacingMaximum New ODF paragraph attributes: loext:word-spacing-minimum loext:word-spacing-maximum New paragraph settings on Text Align pane: Minimum word spacing Maximum word spacing While the desired word spacing got "Desired" label. Note: suggested values of minimum, desired and maximum word spacing are 80%, 100% and 133% (default values e.g. in Adobe InDesign), in narrow columns e.g. 60%, 100% and 150%.

Schemas for Validating ODF Files
Schemas that can be used for validating ODF files
subdirs:
mathml2: W3C MathML 2.0 XML Schema (needed for Math embedded objects)odf1.0,odf1.1,odf1.2: official OASIS RelaxNG schemasodf1.3: current OASIS draft ODF 1.3 RelaxNG schemalibreoffice: 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.
