Re:  Determining whether no single instance of a specif
Hi Mtekel,

I'm encountering the following error:

XSLT Error (javax.xml.transform.TransformerException): Error in
expression not(exists( (b/c) ) ): Unknown system function: exists

Do I need to specify the URI for the XSLT namespace somewhere?

Thanks,
Mark
