Always on LWM. I assume this has to do with UNICODE or not support, but the example in the docs is misleading.
CL-USER 37 > (defparameter *source* (cxml:make-source "<example>text</example>"))
Error: In = of (#\< 254) arguments should be of type NUMBER.
1 (continue) Return a value to use.
2 Supply a new first argument.
3 (abort) Return to level 0.
4 Return to top loop level 0.
Type :b for backtrace or :c <option number> to proceed.
Type :bug-form "<subject>" for a bug report template or :? for other options.
Cheers
