Currently uniqueness or necessity of F17 is unclear. F17 discusses
uniqueness of id attribute
correctness of referencing id or unique identifies (for, headers, usemap attributes)
uniqueness of accesskey attribute
However F77 and F62 discusses most of them.
F77 discusses uniqueness of id
F62 discusses correctness of referencing id or unique identifiers
F68 discusses that in for attribute
F90 discusses that in headers attribute
Remaining issue is uniqueness of accesskey attribute. So we should remove other issuse from F17.
F17: Failure of Success Criterion 1.3.1 and 4.1.1 due to insufficient information in DOM to determine one-to-one relationships (e.g., between labels with same id) in HTML
F62: Failure of Success Criterion 1.3.1 and 4.1.1 due to insufficient information in DOM to determine specific relationships in XML
F68: Failure of Success Criterion 1.3.1 and 4.1.2 due to the association of label and user interface controls not being programmatically determined
F77: Failure of Success Criterion 4.1.1 due to duplicate values of type ID
F90: Failure of Success Criterion 1.3.1 for incorrectly associating table headers and content via the headers and id attributes
