I have just uploaded a new version of the DAVEfunc DTD to the DAVE-ML
website, version 1.9b3, which adds a DSTO-suggested improvement. In
addition to the DTD, the reference manual has an example of how to
invoke the 'atan2' function and fixes documentation links.
<http://daveml.larc.nasa.gov/DTDs.html>
The main change to the DTD is addition of 'discrete' as a supported
interpolation method for tabular data, yielding a stair-step response
from such a function. This came from a suggestion from Geoff Brian of
Australia's DSTO.
The manual also contains an example of how to encode the 'atan2' four-
quadrant arctangent function, which is not directly supported in
MathML2 grammar.
