| Title | Validity error: ID attributes start with number |
|---|---|
| Description | An XHTML file that is well-formed but not valid: although the markup is structurally correct, the ID values for the header cells in thead (table header) are illegal because they start with a number instead of a letter or underscore.
It is not clear how assistive technology responds to this. However, since the header cells define their scope by means of the scope attribute, assistive technologies should not have problems to find the associations between data cells and their headers.
