I have been looking
at the example files on the DAVE-ML website (http://daveml.nasa.gov/examples.html),
however, have had a problem validating these files against the DAVEfunc
DTD. This problem seems to have arisen as a result of the change in the
way Math-ML is defined in the DTD.

Currently, the
calculation element is defined as (DAVEfunc
version 1.7b1):

<!ELEMENT
calculation (mathml2:math)>

<!ATTLIST calculation xmlns:mathml2 CDATA #FIXED 'http://www.w3.org/TR/MathML2'>

<!ATTLIST calculation xmlns:mathml2 CDATA #FIXED 'http://www.w3.org/TR/MathML2'>

Previously, it was
defined as (DAVEfunc version 1.5b3 and
earlier):

<!ENTITY % mathml PUBLIC "-//W3C//DTD MathML
2.0//EN" "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd">

%mathml;

%mathml;

<!ELEMENT calculation
(math)>

I am able to validate the example file,
F16_aero.xml against DAVEfunc v1.5b3, however, when I use DAVEfunc
v1.7b1 the element 'mathml2:math' is expected instead of 'math'. When I
change the 'math' tags to 'mathml2:math' and again try to validate the file
against DAVEfunc v1.7b1, a DTD error is presented saying that the element
'mathml2:math' is undefined. I am unsure how to link this element to
mathml2.dtd.

If anyone is able to explain how to use Math-ML with
the latest version of the DTD, I would be most grateful.

Kind Regards,

Hilary Keating
