Certainly. 

I might as well have said: Someone had said "ICCCM", and nothing more,
after I had asked, in forum, about what would be needed for support of
such that was mentioned in one quote from the XEmacs external-widget 
documentation. It appears that neither the person whom had offered the
vague advice, nor myself -- thereafter -- were really quite clued-in,
about it. I appreciate your explanation.

Good. 

I guess that I've been somehow confused, about what ICCCM reprsents, 
exactly. The ICCCM standard, itself, does seem to have been of some
help, towards that -- for instance, the standards defines the notion
of 'atom', perhaps seeming to imply as if the notion of 'atom' had
been born of ICCCM, rather than of the core XLib protocols. 


I wonder if it may be an incorrect assumption, furthemore, to have
assumed that  ICCCM support would be necessary, for XSession support.



ICCCM and XSession are the headings of two to-do items that I
thought I might manage to address, with any code, in CLX.x

I'm not deterred about such, certainly. It seems that ICCCM support
would still be necessary, in CLX, for to make any use of the  WM_HINTS
property, for instance -- as might be pertinent for a CLX-based
window manager -- and for the handling of clpboard/selection values,
indeed.

XSession support, in CLX, I will not bother about, today, but to note
that I might every try to work about such, so in order to communicate
between an X Session manger and any CLX-using applcations.

I am glad, however, that it may be possible to have an XEmacs 
external-widget, working -- indeed, with GTK -- without any
adaptations made to CLX.

I will try to revisit this, later. 


To be sure: I would formally retract the suggestion of any intention,
for my to work-up, immediately, any support for ICCCM, in CLX.


Thank you
