	Here is what policy says, in part:

          This is a single (generally small) unsigned integer. 
          The <upstream-version> may contain only alphanumerics and the
          characters `.'  `+' `-' `:' (full stop, plus, hyphen, colon) and
          should start with a digit.  If there is no <debian-revision> then
          hyphens are not allowed; if there is no <epoch> then colons are
          not allowed.
          The <debian-revision> may contain only alphanumerics and the
          characters `+' and `.'  (plus and full stop).

	So there is no component that takes merely alphanumerics;
 policy is already quite explicit about this.

     Typically, "letters" means only English letters ({ASCII} A-Z
     plus a-z) but it may also include non-English letters in the
     Roman alphabet, e.g., e-{acute}, c-{cedilla}, the {thorn
     letter}, and so on.  Perversely, it may also include the
     {underscore} character in some contexts.

	I suggest we note that as far as policy is concerned,
 alphanumeric  has the most restrictive definition, namely,
 <character> A decimal digit or a letter (upper or lower case), where
 "letters" means only {ASCII} A-Z plus a-z (This can be an annotative
