Thanks for that report,

interval1 CD is supposed to have that symbol (and did at the time 
otherwise the MathML3 document would have failed link checking and not 
been published...)

I see a version with that symbol in the old svn but there appears to 
have been a regression in moving to git and the github based website.

I'll attach the version from the svn to this message, but clearly we 
need to investigate whether there has been a general regression or 
whether just this file slipped through the cracks.

Sorry about the confusion.
