Ok, i see now where does your problem come from. Try
#use wml::std::page
#use wml::std::box
#use wml::imp::all
<page info title="Test">
<protect pass=4-9>
<fsview src="$(WML_SRC_FILENAME)">
<box>
<import src="$(WML_SRC_FILENAME)">
</box>
</protect>

Explanations stand on wml_p8_htmlstrip(1) : sharp/comment-lines
are removed. In this particular case, i think the right answer should be
<fsview src="$(WML_SRC_FILENAME)">
<box>
<import src="$(WML_SRC_FILENAME)" format=verbatim>
</box>

Indeed, when the attribute format=verbatim is set, one expects that the
file goes unchanged on the output. And i see no reason why files
included via the <fsview> tag are expanded. In fact, i don't understand
what this tag is intended for. Ralf, do you remember what you had in
mind?

To fix these problems, i see 2 solutions:
* Insert <protect pass=4-9>...</protect> in the wml_fmt_verbatim Perl
  subroutine in wml::fmt::verbatim (internally called when the attribute
  format=verbatim is set).
* Don't suppress sharp/comment-lines inside <pre>...</pre>

The latter is more attractive, but the former is more general. You could
then import files containing slice commands, for instance.
If there is no objection, i'll implement the former. If you want, try
the patch below. Apply either to wml_include/fmt/verbatim.src or
....prefix/lib/wml/include/fmt/verbatim.wml
