   The attribute <sgmltag>revisionflag</sgmltag> is usefull to identify the changes between two revisions of a document. This information is managed by dblatex, that adds revision bars in the margin of the paragraphs changed, such like in this <phrase revisionflag="changed">paragraph</phrase>.
   Adding the revision flags can be manual, but its is tedious and error prone. The <ulink url="">diffmk</ulink> tool by Norman Walsh can do the work for you. See <ulink url=""/> for more details about how to use it.
With old changebar packages the revision bars only appear when using the "dvips"
driver. This limitation has been fixed with changebar greater or equal 
to v3.5c.
