For which range please Tony? Err....

\i includes : which is wrong?
\c looks good though! Ah no. Again it's NameChar from
http://www.w3.org/TR/2000/WD-xml-2e-20000814#NT-NameChar
which is more than allowed for xsl:variable @name?

As I read it (or more accurately fail to read it correctly)
It's NameChar less :
followed by (Name less :)+

Simpler version [A-Za-z0-9]+ and the i18N additions,
but I can't get the simpler one working.





It's only matching on the first letter of a variable currently....

<xsl:variable select="$fred"/>

Produces
"xsl:variable"
      	    [f]
"xsl:variable"
      	    [r]
 "xsl:variable"
      	    [e]
 "xsl:variable"
      	    [d]

so something is seriously wrong.
