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.

ODF Import and Export Filter Logic
The main library "xo" contains the basic ODF import/export filter
implementation for most applications. The document is accessed
via its UNO API, which has the advantage that the same import/export
code can be used for text in all applications (from/to Writer/EditEngine).
The filter consumes/produces via SAX UNO API interface (implemented in
"sax"). Various bits of the ODF filters are also implemented in
applications, for example [git:sw/source/filter/xml].
There is a central list of all element or attribute names in
[git:include/xmloff/xmltoken.hxx]. The main class of the import filter
is SvXMLImport, and of the export filter SvXMLExport.
The Import filter maintains a stack of contexts for each element being read. There are many classes specific to particular elements, derived from SvXMLImportContext.
Note that for export several different versions of ODF are supported, with the default being the latest ODF version with "extensions", which means it may contain elements and attributes that are only in drafts of the specification or are not yet submitted for specification. Documents produced in the other (non-extended) ODF modes are supposed to be strictly conforming to the respective specification, i.e., only markup defined by the ODF specification is allowed.
There is another library "xof" built from the source/transform directory, which is the filter for the OpenOffice.org XML format. This legacy format is a predecessor of ODF and was the default in OpenOffice.org 1.x versions, which did not support ODF. This filter works as a SAX transformation from/to ODF, i.e., when importing a document the transform library reads the SAX events from the file and generates SAX events that are then consumed by the ODF import filter.
OpenOffice.org XML File Format
There is some stuff in the "dtd" directory which is most likely related to the OpenOffice.org XML format but is possibly outdated and obsolete.
Add New XML Tokens
When adding a new XML token, you need to add its entry in the following three files:
[git:include/xmloff/xmltoken.hxx][git:xmloff/source/core/xmltoken.cxx][git:xmloff/source/token/tokens.txt]
