Hi,

The MathML 2.0 specification suggests that <mi> render as italic by
default if it contains a single character.

However, it does not specify the behaviour if the <mi> contains a single
digit character, such as <mi> 1 </mi>.

There are many test cases in the MathML test suite which use <mi> in this
fashion instead of <mn> (some of these uses appear to be accidental, but
it is difficult to tell with others).

The sample output for the test cases never makes single digits italic,
regardless of whether or not they are in an <mi>.

Should the specification be updated to say "single letter character"  
rather than just "single character"?

Are the test cases which include such constructions as this:

	<mfrac>
	    <mi> 1 </mi>
	    <mi> 2 </mi>
	</mfrac>

incorrect, or is this a perfectly legitimate use of <mi>?

Thank you,

Michael
