One way to do this would be to make it data driven. In the framework class you build some variable that is the master list of tasks and some well defined calls to initialize the list and then process it. Any framework class can then modify the list as needed and then pass control back. Eg, in the framework: <xsl:variable name="tasks"> <javac/><junit/><javadoc/><jar/><svn/><distrubute/> </xsl:variable> <xsl:template name="init"> <xsl:apply-templates select="tasks" mode="process/> </xsl:template> Then the users of the framework implement "init" with a higher priority and call the same modal templates. They add their own task specific templates with the same mode as needed. Of course, with this approach you're also likely looking at adding some parameter that is the real data to be passed from the main call, to the init and then on to the processing tasks.... -- Peter Hunsberger
