Bad value X for attribute “target” on element “a”: Reserved keyword X used.

The value used in the target property of an <a> element has been identified as a keyword because it starts with an underscore _, but it’s not a valid keyword.

Values starting with an underscore for the target property are used for reserved keywords like _blank, _self, _parent or _top.
