Convertion DocBook to epub - Ambiguous rule match for /

Hi,

if I run the XSLT transformation from Docbook to epub I get:

   [xslt] : Warning! Ambiguous rule match for /

     [xslt] Matches both "/" on line 102 of file:/C:/Users/vogella/workspace/docu/de.vogella.publishing/docbook-xsl-1.76.1/epub/docbook.xsl

     [xslt] and "/" on line 403 of file:/C:/Users/vogella/workspace/docu/de.vogella.publishing/docbook-xsl-1.76.1/xhtml-1_1/chunk-code.xsl

the result seems ok. Not sure if this warning indicates a problem or not. 

I use Apache Ant, Windows7 and docbook-xsl-1.76.1.

Best regards, Lars
