Showing information
===================

   Commands for showing information obtained by parsing the buffer.

`C-c C-c'
     Shows in the message area: context at point, if in a tag or in
     mixed content and the open elements (`sgml-show-context').

`C-c C-w'
     Shows what element the character after point (under the cursor)
     belongs to; also shows context of element (`sgml-what-element').

`C-c C-t'
     List contextually valid tags (`sgml-list-valid-tags').  Displays
     information about current element, all valid end-tags, valid
     start-tags in current element, and start-tags valid at this point
     but in other elements together with the tags omitted.

   You can make the mode-line display the name of the current open
element by setting the `sgml-live-element-indicator' variable.  Setting
this will make all commands slower due to the work needed to keep the
mode-line up to date.

 - User Option: sgml-live-element-indicator
     If non-nil, indicate current element in mode line.

     NOTE: Setting this implies that every command can cause a parse.
