Strange errors, e.g.: 1. Differentiation between SRC and src: Line 642, Column 266: Attribute "SRC" is not a valid attribute. Did you mean "src"? en" value="true"></param><embed src="http://www.youtube.com/v/xVjzn81d26k& 2. Commonly used <Embed> attributes are rejected: Line 642, Column 455: Attribute "ALLOWFULLSCREEN" is not a valid attribute /x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed>< The point of my adding this bug report is to note the fact that I cannot fully validate any page that has a Youtube video embedded in it, which is frustrating.
1) is a known bug which will be fixed in the next validator release. 2) For <embed> there's nothing the validator can do, see http://validator.w3.org/docs/help.html#faq-flash The error message for 2) is misleading though (assuming it appears alone and there's no error for the <embed> element itself). Can you provide an URL to a document with which this can be investigated further?
Misleading suggestions should be gone in 0.8.6.
