Re: Translating "("

although it doesn't really help in this case much as you'd still have to
concat() those variables with the rest of the string. what you could do
though is to put the whole string in a variable of this form

<xsl:variable name="x">'&#160;/(),"</xsl:variable>

then you can use

select="translate(normalize-space(ln:term),$x,'_')
