Using custom profiling attributes from the command line

Hi all,

I'm trying to define my custom profiling attributes from the command line rather than from within a customization layer and having problems. 

I've defined my custom attributes according to http://www.sagehill.net/docbookxsl/AddProfileAtt.html and they function fine when called via a customization layer 

(e.g. <xsl:param name="profile.document" select="'DDD'"></xsl:param> 

but fail when I call them via the command line 

(e.g. java -jar saxon.jar  -o D:\XML-Public\docs\saxon_temporary.fo D:\XML-Public\docs\saxon_temporary.xml ../../../depend/DocbookXSL/docbook-xsl-1.73.2/fo/customization_layers/Profile_PMC_Content.xsl  profile.document="DDD"

The standard docbook profiling attributes work fine when called; only the custom profiles that I've defined fail. Is there an extra step needed to pick them up from the command line?

Thanks,
Jeff.
