 #!CommitTicketReference repository="" revision="51963"
 KSES: Add options for restricting tags based upon their attributes.

 This change adds two now attribute-related config options to KSES:
 - An array of allowed values can be defined for attributes. If the
 attribute value doesn't fall into the list, the attribute will be removed
 from the tag.
 - Attributes can be marked as required. If a required attribute is not
 present, KSES will remove all attributes from the tag. As KSES doesn't
 match opening and closing tags, it's not possible to safely remove the tag
 itself, the safest fallback is to strip all attributes from the tag,
 instead.

 Included with this change is an implementation of these options, allowing
 the `<object>` tag to be stored in posts, but only when it has a `type`
 attribute set to `application/pdf`.

 Props pento, swissspidy, peterwilsoncc, dd32, jorbin.
 Fixes #54261.
