[CL] Misleading passage about XCL

[Eric Peterson]

Dr. Sowa;

Thanks for your tireless efforts with CL.

Regarding your question about XCL use, I've written and XCL subset to Prolog
translator that I hope/expect to use when my team finds a sufficiently
scalable logic programming environment for our semantic store.

I agree with all of your technical criticisms of XML.  But my customers and
colleagues are very comfortable with W3C recommendations and XML in
particular. So the presence of XCL in your effort has increased my
confidence that CL's wheels are on the ground and capable of traction in my
world.

I'm not weighing in on the wordsmithing here.  I would just prefer not
seeing XCL support diminish in any way until there is a new web interchange
lingua Franca to replace XML.

Sorry if I'm reading too much into this thread.


Best,

-Eric
