I s'pose, but it's so easy to write tags in DSP that I don't see it
as a problem.  Implementing a tag like <xx:foo arg1="bar"> ... </xx:foo>
is just

define body tag foo in some-taglib
    (page :: <dylan-server-page>, response :: <response>, do-body :: <function>)
    (arg1 :: <string>)
  format(output-stream(response), "blah blah");
  if (frob(arg1))
    do-body();
  end;
end;

I think for quick hacks putting code directly in the web page is
useful, but the cost of having to drag around the Dylan compiler
and the complexity of implementation outweigh that for me.
