[xsl] Collation in another language

["Mark" <mark@xxxxxxxxxxxx>]

I am not sure if this question belongs here or not, but hope for an answer. 
I need a collator that puts bchb between bHb and bIb. In another email from 
this list, Jirka Kosek gave me a link to some code he had written a very 
long time ago for docbook, but it is not at all clear to me how to use his 
code (located here:)

I do not know java, but cobbled together a Czech language collator from 
notes I found on the web (if there is c java Czech collator already 
available, I donbt know how to find it). I call the collator in my style 
sheet:

<xsl:variable name="sorting-collation" 
select="'http://saxon.sf.net/collation?class=CzechCollation'"/>
 <xsl:template match="List">
   <List>
     <xsl:for-each-group select="Word"  group-by="@word">
       <xsl:sort select="@word" collation="{$sorting-collation}"/>
......

And my java code is below: It does not put the bchb digraph in the right 
place
