The following hints correspond to well-formed XML elements in ODF:
RES_TXTATR_INETFMT, RES_TXTATR_CJK_RUBY, RES_TXTATR_META, RES_TXTATR_METAFIELD,
RES_TXTATR_CONTENTCONTROL
The writer core must ensure that these do not overlap; if they did,
the document would not be storable as ODF.
Also, a Hyperlink must not be nested within another Hyperlink,
and a Ruby must not be nested within another Ruby.
The ODF export in xmloff will only put a hyperlink into a ruby, never a ruby
into a hyperlink.
Unfortunately the UNO API for Hyperlink and Ruby consists of the properties
Hyperlink* and Ruby* of the css.text.CharacterProperties service. In other
words, they are treated as formatting attributes, not as content entities.
Furthermore, for API users it is not possible to easily test whether a certain
range would be overlapping with other nested attributes, and most importantly,
<em>which ones</em>, so we can hardly refuse to insert these in cases of
overlap.
It is possible to split Hyperlink and Ruby into multiple portions, such that
the result is properly nested.
meta and meta-field must not be split, because they have xml:id.
content controls should not split, either.
These constraints result in the following design:
RES_TXTATR_INETFMT:
always succeeds
inserts n attributes split at RES_TXTATR_CJK_RUBY, RES_TXTATR_META,
RES_TXTATR_METAFIELD
may replace existing RES_TXTATR_INETFMT at overlap
RES_TXTATR_CJK_RUBY:
always succeeds
inserts n attributes split at RES_TXTATR_META, RES_TXTATR_METAFIELD
may replace existing RES_TXTATR_CJK_RUBY at overlap
may split existing overlapping RES_TXTATR_INETFMT
RES_TXTATR_META:
may fail if overlapping existing RES_TXTATR_META/RES_TXTATR_METAFIELD
may split existing overlapping RES_TXTATR_INETFMT or RES_TXTATR_CJK_RUBY
inserts 1 attribute
RES_TXTATR_METAFIELD:
may fail if overlapping existing RES_TXTATR_META/RES_TXTATR_METAFIELD
may split existing overlapping RES_TXTATR_INETFMT or RES_TXTATR_CJK_RUBY
inserts 1 attribute
The nesting is expressed by the position of the hints.
RES_TXTATR_META and RES_TXTATR_METAFIELD have a CH_TXTATR, and there can
only be one such hint starting and ending at a given position.
Only RES_TXTATR_INETFMT and RES_TXTATR_CJK_RUBY lack a CH_TXTATR.
The interpretation given is that RES_TXTATR_CJK_RUBY is always around
a RES_TXTATR_INETFMT at the same start and end position (which corresponds
with the UNO API).
Both of these are always around a nesting hint with CH_TXTATR at the same
start and end position (if they should be inside, then the start should be
after the CH_TXTATR).
It would probably be a bad idea to add another nesting hint without
CH_TXTATR; on the other hand, it would be difficult adding a CH_TXTATR to
RES_TXTATR_INETFMT and RES_TXTATR_CJK_RUBY, due to the overwriting and
splitting of existing hints that is necessary for backward compatibility.
