[Xpipe-users] XComponent <parameters> working?

[Roger L. C. <cos...@mi...>]

I am trying to use the parameter element in xcomponents.  I have created
an xcomponent which changes the name of an element, where the name of
the element to be replaced and its replacement value are specified as a
parameter [see the xcomponent below].  The problem is that the
parameters don't seem to be getting to my xcomponent's code (a
stylesheet).  Am I doing something wrong, or is it simply that
parameters have not been implemented yet?

My second question is more general, on how parameters get delivered to
an xcomponent's code.  I assume that when the code is xslt the
parameters get delivered just as stylesheet parameters.  Right?  What if
the code is Java?  Do the parameters get delivered as parameters to the
main routine, i.e., 

public static void main(String[] args)

The parameters will be in the args array?

As I dig deeper I am getting more and more excited about this
technology.  This is the right approach I feel.  I wish that I had the
time to help implement the core pieces.  Timeliness is crucial, I
think.  /Roger
