 25.12 SGML and HTML Modes
 =========================
 
 The major modes for SGML and HTML provide indentation support and
 commands for operating on tags.  HTML mode is a slightly customized
 variant of SGML mode.
 
 ‘C-c C-n’
      Interactively specify a special character and insert the SGML
      ‘&’-command for that character (‘sgml-name-char’).
 
 ‘C-c C-t’
      Interactively specify a tag and its attributes (‘sgml-tag’).  This
      command asks you for a tag name and for the attribute values, then
      inserts both the opening tag and the closing tag, leaving point
      between them.
 
      With a prefix argument N, the command puts the tag around the N
      words already present in the buffer after point.  Whenever a region
      is active, it puts the tag around the region (when Transient Mark
      mode is off, it does this when a numeric argument of −1 is
      supplied.)
 
 ‘C-c C-a’
      Interactively insert attribute values for the current tag
      (‘sgml-attributes’).
 
 ‘C-c C-f’
      Skip across a balanced tag group (which extends from an opening tag
      through its corresponding closing tag) (‘sgml-skip-tag-forward’).
      A numeric argument acts as a repeat count.
 
 ‘C-c C-b’
      Skip backward across a balanced tag group (which extends from an
      opening tag through its corresponding closing tag)
      (‘sgml-skip-tag-backward’).  A numeric argument acts as a repeat
      count.
 
 ‘C-c C-d’
      Delete the tag at or after point, and delete the matching tag too
      (‘sgml-delete-tag’).  If the tag at or after point is an opening
      tag, delete the closing tag too; if it is a closing tag, delete the
      opening tag too.
 
 ‘C-c ? TAG <RET>’
      Display a description of the meaning of tag TAG (‘sgml-tag-help’).
      If the argument TAG is empty, describe the tag at point.
 
 ‘C-c /’
      Insert a close tag for the innermost unterminated tag
      (‘sgml-close-tag’).  If called within a tag or a comment, close it
      instead of inserting a close tag.
 
 ‘C-c 8’
      Toggle a minor mode in which Latin-1 characters insert the
      corresponding SGML commands that stand for them, instead of the
      characters themselves (‘sgml-name-8bit-mode’).
 
 ‘C-c C-v’
      Run a shell command (which you must specify) to validate the
      current buffer as SGML (‘sgml-validate’).
 
 ‘C-c <TAB>’
      Toggle the visibility of existing tags in the buffer.  This can be
      used as a cheap preview (‘sgml-tags-invisible’).
 
    The major mode for editing XML documents is called nXML mode.  This
 is a powerful major mode that can recognize many existing XML schema and
 use them to provide completion of XML elements via ‘M-<TAB>’, as well as
 on-the-fly XML validation with error highlighting.  To enable nXML mode
 in an existing buffer, type ‘M-x nxml-mode’, or, equivalently, ‘M-x
 xml-mode’.  Emacs uses nXML mode for files which have the extension
 ‘.xml’.  For XHTML files, which have the extension ‘.xhtml’, Emacs uses
 HTML mode by default; you can make it use nXML mode by customizing the
 variable ‘auto-mode-alist’ (Choosing Modes).  nXML mode is
 described in its own manual: nXML Mode (nxml-mode)Top.
 
    You may choose to use the less powerful SGML mode for editing XML,
 since XML is a strict subset of SGML.  To enable SGML mode in an
 existing buffer, type ‘M-x sgml-mode’.  On enabling SGML mode, Emacs
 examines the buffer to determine whether it is XML; if so, it sets the
 variable ‘sgml-xml-mode’ to a non-‘nil’ value.  This causes SGML mode’s
 tag insertion commands, described above, to always insert explicit
 closing tags as well.
