<!-- 

addImageRefs.xsl: take WriterImageNames.xml output created by 
getImageNameData.xsl and insert the href values into the right 
places in a DocBook file created by OpenOffice Writer 3.1.

If this had to scale way up it would be worth using xsl:key to 
speed the lookups. See http://www.xml.com/lpt/a/933.
