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'>

 

 

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;

<!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,

Ms. Keating,

I took out the explicit namespace entity for MathML in version 1.6b1. That <!ENTITY> directive inserts the whole mathml2.dtd document into the DAVE-ML

DTD at that point in the code, which seemed wasteful; I tried to accomplish the same goal by adding what I thought was the appropriate default attribute to the <math> element.

I'm sending you separately a test DTD to see if that fixes things.

 

What editor or tool are you using to validate?

Thanks,
