You specify the type of body that is valid for a tag by using the body-content element. This element is used by the web container to validate that a tag invocation has the correct body syntax and is used by page-composition tools to assist the page author in providing a valid tag body. There are three possible values:
tagdependent: The body of the tag is interpreted by the tag implementation itself, and is most likely in a different language, for example, embedded SQL statements.
empty: The body must be empty.
scriptless: The body accepts only static text, EL expressions, and custom tags. No scripting elements are allowed.
