URL where the problem was first discovered

Relevant code

<frameset cols="*,*">
  <frame src="support/viewport-004-firstcanvas.htm"></frame>
  <frame src="support/viewport-004-secondcanvas.htm"></frame>
      <p>Test passes if this text is visible.</p>

W3C Markup Validator version


The W3C validator error message
{ end tag for element "FRAME" which is not open (check earlier errors) .} 

seems to indicate that start tag <frame> is not seen.

I have checked with other validators ( WDG, , ) and the error message is the same.

</frame> end tag is optional:
<!ELEMENT FRAME - O EMPTY              -- subwindow -->

I can create a reduced testcase if required, requested.

regards, Gérard

| The hyphen and the following "O" indicate that the end tag can be omitted, but
| together with the content model "EMPTY", this is strengthened to the rule that
| the end tag must be omitted.

Thank you!

Marking as VERIFIED
