Another reason why I'd compare ASN.1 to SGML rather than XML is that,
like SGML, ASN.1 seems to be schema centric: it looks like you can't do
anything in ASN.1 without designing a schema first like you can't do
much with SGML without designing a DTD first.

Since the breakthrough of XML versus SGML is the fact that schemas are
now optional, isn't ASN.1 a regression in this respect?

I'd say that this might be a reason why ASN.1 isn't binary XML, it would
rather be binary SGML!


Don't you think all these XML schema languages should work together?
