the msub element is not implemented.  I get something proper when I use sub, but that's an xhtml element and inappropriate.


Reproducible: Always

Steps to Reproduce:
1. use the msub operator in an xhtml document in mathml. for instance,
<m:math>
 <m:mrow>
     <m:mi>log</m:mi>
     <m:msub>b</m:msub>
     <m:mi>n</m:mi>
  </m:mrow>
</m:math>
and <body xmlns:m="http://www.w3.org/1998/Math/MathML">
2.
3.
Actual Results:  
loginvalid markupn

Expected Results:  
log n
   b

msub is defined in the mathml 3.0 specification.  please implement. thank you. http://www.w3.org/TR/2010/PR-MathML3-20100810/Overview.html
it is possible I am using MathML incorrectly, nobody has told me otherwise, but I doubt it.

mathml 3.0 test case of msub using xhtml 1.1

attached the requested test case.  it's essentially a boiled down version of the URL above.  does the same thing.  right at the msub, complains.

corrected mathml 3.0 test using xhtml1.1 - works

my former code was incorrect. this *is* correct.  took me a while to figure out the spec's wording.  it's not intuitive.
