First that I heard of, first that I see it. And while digging the
documentation for I found the following in mp4h(1):
similar to HTML, with tags and attributes. One important feature has
no equivalent in HTML: comments until end of line. All text following
three colons is discarded until end of line, like
;;; This is a comment
I see. So ;;; is *no* comment sign for wml, it is a comment sign for
wml_p2_mp4h. This means that stuff inside these "comments" are still
evaluated through wml_p1_ipp, see below.

Not really:
Comments
IPP provides support for up-to-end-of-line comments. This type of com-
ment is like the one found in Bourne-Shell or Perl, i.e. any line which
starts with a sharp symbol (`"#"') is entirely (i.e. including the new-
line at the end) removed from the input. Additionally these lines can
have whitespaces in front of the sharp symbol. When you really need a
sharp symbol at the start of a line you can use "\#", i.e. prefix it
with an escaping backslash.
(from wml_p1_ipp(1))
So when using ;;; instead of # as comment leader you are passing the
content through ipp which does expand $(foo) style variables. I would
suggest to switch to ipp style comments instead of mp4h style comments
to avoid this (and maybe improve compile performance a little bit, I
don't know).
But that is just my opinion....
