AbiWord Markup Language DTD
Last updated January 17, 2007
(but still far from complete and correct)
Currently, this document is intend for reference purposes only,
and should not be interpreted as an absolute guide to the
AbiWord file format. A more comprehsive view can be gained
from the code in files ie_exp_AbiWord_1.cpp and
ie_imp_AbiWord_1.cpp These are currently definitive. Other
documentation is available in docs/AbiWord_DocumentFormat.abw
