$levelreference is an RTF which I populated by using
xsl:for-each on a key. My XML is very complex so I am
using lots of keys to get the appropriate result.
Again also I can see some performance degradation
because of usage of lost of xsl:for-each. Anyway I
will look into the performance later.
Thanks for your help.
