I refer you to the HTML 4.0 specification for details, see:

    http://www.w3.org/TR/REC-html40/present/frames.html

for information on frames. The W3C validator can check you
html using different DTDs - the strict DTD for 4.0 and
the looser one which includes frames. You can see how to
get the right one using the info at the top of the page at:

    http://validator.w3.org/

I checked the geocities home page with my HTML tidy utility
(available via my home page) and saw the following errors:

Parsing "geocities.html"

Tidy is somewhat more forgiving than the validator and doesn't
complain about the missing type attribute for script. The HTML
working group couldn't reach a concensus that the language attribute
as an acceptable alternative to type.  Geocities are using image
maps that are inaccessable to people with non-visual browsers or who
cannot see the images. They do provide text menus but only at the
bottom of the page. They use tables for visual layout in a way that
creates accessibility problems. The missing summary attribute should
be used to describe the structure of the table. Geocities is also
rather lax about its use of font elements.
