I'm working on formalizing the definitions in the SPARQL
spec[1], and since my larch tools[2] are getting crufty and
I just saw a bunch of nifty MathML products at XML 2004,
I'm trying to use MathML. I'm copying from the nifty
MathML test materials
and using the stylesheet there
which seems to work pretty well in Mozilla firefox.

My work-in-progress is

For example, I encoded

  The set of RDF Terms, RDF-T, is RDF-U union RDF-L union RDF-B.


  <math xmlns="http://www.w3.org/1998/Math/MathML"> 
    <declare type="set">
      <ci> RDF_T </ci>
	<ci> RDF_U </ci> 
	<ci> RDF_L </ci> 
	<ci> RDF_B </ci> 

expecting to get something like


but the test materials say:

          	declare test (no visible rendering)"

Am I just using the wrong stylesheet to lay out my MatML?
Or is there some other preferred mathml syntax for "Let X be..."?
