* lisp/nxml/nxml-mode.el (nxml-complete): Obsolete. (nxml-completion-at-point-function): Remove. (nxml-mode): Don't set completion-at-point-functions. * lisp/nxml/rng-nxml.el (rng-nxml-mode-init): Set it here instead. (rng-completion-at-point): Rename from rng-complete and mark it non-interactive. It is now to be used as completion-at-point-function. (rng-complete-tag, rng-complete-end-tag, rng-complete-attribute-name) (rng-complete-attribute-value): Don't perform completion, but return completion data instead. (rng-complete-qname-function, rng-generate-qname-list): Add a few arguments, previously passed via dynamic coping. (rng-strings-to-completion-table): Rename from rng-strings-to-completion-alist. Don't return an alist. Don't both sorting and uniquifying. * lisp/nxml/rng-util.el (rng-complete-before-point): Delete function. (rng-completion-exact-p, rng-quote-string): Delete functions. * lisp/nxml/rng-valid.el (rng-recover-start-tag-open) (rng-missing-attributes-message, rng-missing-element-message) (rng-mark-missing-end-tags): Use explicit ".." in formats rather than calling rng-quote-string everywhere.
