I tried adding:

alias date_time_docs : ../../libs/date_time/xmldoc//date_time/<location>bin2 
:
        <format>pdf:<xsl:param>xep.extensions=1
        <format>pdf:<xsl:param>fop.extensions=0
        <format>pdf:<xsl:param>fop1.extensions=0

;

to doc/pdf/Jamfile.v2 but got a whole load of bbv2 errors:
