when the closing > of a tag is missing it isn't reported (at least not for tables) I had used "</table" by mistake, missing the ending >, but it wasn't flagged as an error, and the page passed validation
For XHTML if the Validator does not report it this is a known limitation as pointed out in the Validation results (look for the note about XML support); for HTML this is allowed and it would be wrong to report an error. We are working on adding warnings for such cases.
