## 6 SGML Declaration

PSGML does not understand the SGML declaration, it accepts one in the file but it is ignored. If you have the SGML declaration in another file you can make `sgmls` use it when you use the `C-c C-v` (`sgml-validate`) command (see Validate).

PSGML has some options in what features it uses and what markup it creates. You have to set these options to make PSGML’s behavior consistent with your SGML declaration and personal preferences.

User Option: sgml-omittag

  Set this to `t` if the SGML declaration has ‘`OMITTAG YES`’ and to `nil` otherwise.

User Option: sgml-shorttag

  Set this to `t` if the SGML declaration has ‘`SHORTTAG YES`’ and to `nil` otherwise.

User Option: sgml-namecase-general

  Set this to `t` if the SGML declaration has ‘`NAMECASE GENERAL YES`’ and to `nil` otherwise. I.e., this controls whether names, except entity names, will be case insensitive (translated to upper case).

User Option: sgml-always-quote-attributes

  If non-nil, quote all attribute values inserted after finishing edit attributes. If this variable is `nil` and `sgml-shorttag` is non-`nil`, attribute values that consists of only name characters will not be quoted.

User Option: sgml-minimize-attributes

  Determines minimization of attributes inserted by edit-attributes. If non-nil, omit attribute name if the attribute value is from a token group. If `max`, omit attributes with default value. Minimization will only be done if they produce legal SGML (assuming `sgml-omittag` and `sgml-shorttag` are set correctly).
