Frames FAQ: Validating documents with frames

How do I validate documents with frames?

You can't. The public validators do not have a DTD that has support for frames. If you use your own DTD, you can make the following changes to it to add support for frames:

Replace <!ENTITY % html.content "HEAD, BODY, PLAINTEXT?"> with <!ENTITY % html.content "HEAD, (BODY|FRAMESET)">
Add the TARGET attribute (with a content of CDATA) to the elements A, AREA, BASE and FORM.

Add the following new declarations:

<!ENTITY FRAMESET - - (FRAMESET, FRAME, NOFRAMES)+ >
<!ATTLIST FRAMESET
    ROWS          CDATA  #IMPLIED -- Comma separated list of rows --
    COLS          CDATA  #IMPLIED -- Comma separated list of columns --
