Saxon -dtd:off

Hello All
I am trying my best to not go along the catalog side and instead do
the short cut of escaping the validation step... I do the following

java -Xms100M -Xmx500M -jar C:\Temp\saxon9.jar -dtd:off
C:/Temp/tmp/SampleXML.xml  work/identity.xsl

where the SampleXML has a Doctype declaration..

I expected that the above should work..
The result still says that the DTD is not found.. Am I missing something ??
