It looks like the xmlrpc.tcl file no longer validates properly at validator.xmlrpc.com. Didn't they tweak the specs a little while back? It look like it's related to the multi-level nesting stuff, but I'm not sure b/c reading through the proc is making my head spin...*grin*...great job!
If you're getting it to validate, please let me know...maybe I've screwed something up. If not, any ideas on fixing? I'd LOVE to use it...(heck, I'm gonna use it...it's still partially validating even now...)
