[xsl] XPath to test that a middle name consists of a letter followed by

Hi Folks,

Here is an example of a valid middle initial:

        <MI>H.</MI>

I need an XPath expression to check that the value of <MI> is an uppercase 
letter of the English alphabet followed by a period symbol, and nothing else.

This XPath expression seems to work fine:

        ((matches(MI, '[A-Z]\.')) and (string-length(MI) eq 2))

I am wondering if there is a better (simpler, shorter, more robust) XPath 
expression?
