I have just uploaded a new version of the DAVEfunc DTD to the DAVE-ML
website, version 1.9b2, which addresses several suggested
improvements and fixes a bug or two.
<http://daveml.larc.nasa.gov/DTDs.html>
The complete list of changes is found in the updated reference
manual, either in PDF or HTML format, but the major items are:
Added an enumeration attribute to the independentVar elements to
indicate that the function should be interpolated with a quartic
spline
Added a reference to a most useful Wikipedia page that describes
spline interpolation in detail
Corrected a missing ENTITY element that now properly includes the MathML2 DTD
Added two ungridded table examples to the reference manual
Most of these changes came from suggestions from Geoff Brian of
Australia's DSTO; that agency has embraced DAVE-ML and is now
providing a C++ API library, Janus, available under Open Source
license
<http://www.dsto.defence.gov.au/research/4675>
The manual also contains two new examples; these are a result of the
AIAA's review of DAVE-ML as a proposed standard for simulation model
exchange.
I was actually working on the final checkout of the new DTD when the
message from Dr. Cignoni was posted; that was a pleasing serendipity
because this revised DTD will address most if not all of the bugs he
and his GeneSim project team found.

Thanks for the helpful suggestions!
