I can confirm that this bugs out. I know nothing about the nxml code, but I did notice that about half of the rng variables are defined thusly: (defvar rng-validate-up-to-date-end nil "Last position where validation is known to be up to date.") (make-variable-buffer-local 'rng-validate-up-to-date-end) But the ones that it reports as failing here depends on variables like `rng-pending-contents', which are not buffer-local. So to test blindly, I made that also buffer-local... and then the entire process failed with a backtrace, so that's not the solution. :-) But I do think it's really suspicious that some of those variables are buffer-local while others aren't. Perhaps somebody who knows how that machinery works could have a peek at it. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
