The IFRAME tag

On a recent project our team has decided to use a strict HTML 4.01 DOCTYPE
which is working well using your validation service and testing in browsers
both old and new.

 

Our design requires the use of IFRAMEs and I note that the validation
service does not allow the use of IFRAMEs. I think that odd since I first
learnt of IFRAMEs on your site and used the code your site provided to write
them.

 

Please could you tell me if there is an equivalent tag to IFRAME, if it is a
bug in your validator or whether another DOCTYPE is required? I tried using
the frameset DOCTYPE to no avail as it dislikes the body tag.

 

I am sorry if this is an easy question; I have no real prior knowledge of
DOCTYPING and would like to make my code 100% compliant as we are
considering the use of mobile internet devices.

 

Thank you for providing such a useful service at no cost.
