MathML Test Files are cheating!

Hi,

I've had a look at the MathML Test Files. I think
some tests are cheating!
The source given sometimes refers to entities like
ⅇ , γ , &infinity; ,  ect..., but
the actual source uses codes like ⅇ ,
γ or  ∞ .
(cfr page:
http://www.w3.org/Math/testsuite/testsuite/Content/To
kenElements/cn/cn2.xml )

MathML is a great project, I whish we can soon use it
on the web.

Thanks
