No I put in spaces to make sure it showed up (sorry, I should have said) 
some mail readers try to be "clever" and replace character references by 
the character.

yes.

<xsl:when test="number('12')=number('12')">
is true, because the string '12' casts to a number.

<xsl:when test="number('xy')=number('xy')">
is false as the string 'xy' casts to the special value NaN which is not 
equal to anything, even itself.

so

<xsl:when test="number(.)=number(.)">

is true just if the string value of the current node is the lexical form 
of a number.
