I created 2.0 xslt and added this 
        <xsl:result-document validation="strict">

believing running the following on the command line
net.sf.saxon.Transform -dtd:on
might check the output document. But after investigating,  appears net.sf.saxon.Transform only checks source documents against dtd?

If I wanted to check my output xml documents conform to dtd, how would I use saxon jar on command line for this, if possible?
Or another command line util, if possible?
