er no, if you'd tried that you would have found that it didn't work.
(You get  ⁢ as th eoutput unless you are writing
text rather than xml)

Going back to the original posting

No that just defines &inverti; to be &InvisibleTimes; which is not
defined. What you need to do is define "&InvisibleTimes;
preferably by just including the.ent files from the mathml.dtd
in which case you get character data output.

However unfortunately you currently _need_ to have &xxx; syntax for
amaya (which is certainly a bug in amaya, which I keep meaning to
report)
so for amaya I use a special set of entity definitions that look like 

<!ENTITY InvisibleTimes
   "<xsl:text
   disable-output-escaping='yes'>&amp;InvisibleTimes</xsl:text>" >
