4.6.2 Changed Regions
For every changed region of a document,
there is one entry in the list of tracked changes. This entry contains a list
of all changes that were applied to the region. The start and end of this
region are marked by the start and end elements that are described in the next
section.
<define name="text-changed-region">
<element
name="text:changed-region">
<ref
name="text-changed-region-attr"/>
<ref
name="text-changed-region-content"/>
</element>
</define>
Change ID
Every element has an ID. The elements that mark the
start and end of a region use this ID to identify the region to which they
belong.
<define name="text-changed-region-attr"
combine="interleave">
<attribute
name="text:id">
<ref
name="ID"/>
</attribute>
</define>
