It won't.
There's no DTD for XHTML5 and writing one would be a bad idea. Also,
the conformance checking service runs the XML parser in the non-
validating mode without resolving external entities, because XHTML
browsers generally do not perform DTD validation and do not resolve
external entities and it would be a bad idea for a conformance
checker to examine a document tree that is different from what
browsers see.

It wouldn't. It would be part of the problem! (The document could
declare a random attribute to be of type ID in the DTD.)
