It's not obvious what happened (in the absence of a URL),
but presumably there was a construct <!-- somewhere so that
we are inside a comment declaration, and a comment was terminated
by the "--", and then the following "?" is indeed an error.

It is not _possible_ to include "---" or even "--" within a comment,
since "--" is a comment terminator. Inside a comment declaration,
on the other hand, "---" is correct in suitable circumstances, if
immediately followed by yet another "-":
<!--foo----bar-->
My suggestion of the wording:
"A common error is to try to use two or more adjacent hyphens
in a comment text, as in <!-- hello -- there! -->. In this case,
the second "--" terminates a comment."
