I am running the following command (on windows XP) to validate an xml file against the DocBook DTD.  (I am using SaxonB8-1-1.)

java net.sf.saxon.Transform -w2 -v .\XML_Files\BOOK_NOSNumber1March1997.xml DoNothingXslt.xsl

I get the following warning errors:

Warning: on line 2 column 16 of file:/C:/SIL/digpub/ll/src/LLL2DocBook/DoNothingXslt.xsl:
 Error reported by XML parser: Document is invalid: no grammar found.

Warning: on line 2 column 16 of file:/C:/SIL/digpub/ll/src/LLL2DocBook/DoNothingXslt.xsl:

 Error reported by XML parser: Document root element "xsl:stylesheet", must match DOCTYPE  root "null".


The first two lines of DoNothingXslt.xsl are as follows:

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">



Is there something wrong with how I am going about using this command when having it validate an xml file against a DTD?
 
It appears to me that it is trying to validate the xsl file since it is complaining about not finding a grammar for the xsl file.  
If I run the command and do not include an xsl file the command will not run so that is not the solution to this.

Should I just be ignoring the warning/error?
