You are clearly supplying the parameter to the template incorrectly, but
since you haven't shown us the calling code, it's hard to tell you
what's wrong with it.

> I am implementing a look up table for localizable

> <?xml version="1.0"?>
> <strings>
>   <string key="String.One">First String</string>
>   <string key="String.Two">Second String</string>
> </strings>
> 
> I do this to load the string table in my main xslt:
>   <!-- Load the string table -->
>   <xsl:variable name="stringTable" 
> select="document($stringTableFileName)"/>
> where $stringTableFileName is a parameter to the style
> sheet.

> To test things I used variables like this:
> <xsl:variable name="title" 
> select="$stringTable/strings/string[@key='String.One']"/>

>     <xsl:variable name="lookupString" 
> select="$stringTable/strings/string[@key=$key]"/>

>         <!-- Return the found string -->
>         <xsl:value-of select="$lookupString"/>
>       </xsl:when>
>       <xsl:otherwise>
>         <!-- Return a string indicating what key could
> not be found -->
>         <xsl:text>!</xsl:text><xsl:value-of
> select="$key"/><xsl:text>!</xsl:text>
>       </xsl:otherwise>
>     </xsl:choose>
>   </xsl:template>
