Something along the lines of

<xsl:param name="debug" select="f"/>

...

<xsl:if test="debug='t'">
  <xsl:message>*****</xsl:message>
</xsl:if>

embedded appropriately in your code?  Ugly, I know, but standard :-)

Not when working with printouts.  A debugger is most likely a bit off.

Wonder, though.  How easy would it be to interface e.g. Saxon to the debugger interface in Emacs?  That would be a step in the right direction.

I would like seeing it.  Any one have a hint?
