DTD vs. XML Schema

Doesn't that violate the requirement that the regular expressions in an element declaration must be "deterministic"? I haven't found an XML parser that complains about "nondeterminism" though.
Their stuff has a keypair as well as a certificate for that keypair issued by AMI (presumably).
If you can't sign messages using a private key that
you can prove to be good (the certificate), then
no-one will believe you. You can't keep sending
out old messages. Those kinds of replay attacks
will be prevented with nonces.
Depends on your definition of a language, which in
turns depends on your community. Common definitions:
Language: a set of strings (drawn from some set called an alphabet).
Programming language: a language with an operational semantics (a description of the runtime behaviour of those strings, could be defined by an implementation).
XML and XML Schema are both languages according to this definition. In addition, XML Schema has a semantics that associates a subset of the
set of all XML documents to every XML Schema.
Try
Relax NG. Relax was
developed in Japan and is quite popular there.
TREX is James Clark's attempt at a type system that is
more flexible than DTDs but less complicated than
XML Schema. Relax NG is the merger of those two
systems. It looks appealing but I have not used it in anger yet.

I don't think so. The point of TCPA and Palladium is that you can't emulate everything
that the processor does, because the processor
will have an embedded keypair that is issued
(and signed) by Intel. You won't be able to
(easily) extract the private key from the
processor (tamper-resistant hardware), nor
will you be able to use your own keypair
because you won't be able to offer up a
certificate issued by Intel.
With TCPA and Palladium your execution environment can demonstrate that it is trustworthy (to MPAA/RIAA/Microsoft, insert your favorite group of
untrustworthy suits!). The designers of TCPA and Palladium are well aware of VMWare, Plex, and the other games that can be played with environments,
and have defended against them.
You will not be able to do this once Palladium on TCPA arrives. It will allow Sony's key servers
to check that your environment is trustworthy (from Sony's perspective) before sending out a key.
Apparently UAE users that only want to read
Amiga disks do not need one. This program
disk2fdi claims to let you read Amiga disks if you have
two floppy drives (by buggering around, swapping between the two drives in the middle of a sequence of commands, from what I understood of their explanation). I have not tried it yet, but I really hope that it works, not because it would be convenient, but because it appears to be such a neat hack.
Hey, if Freeh managed to get a law enforcement
backdoor
into every crypto device and it applied
to Palladium and other DRM systems
implemented in hardware, then those systems
would be considerably more vulnerable!

Yes, StarOffice 6.0 includes a filter for WordPerfect 8 documents according to the
technical FAQ. According to the general FAQ (and somewhere else that I can't find right now), the WordPerfect filter is licensed from another company, so it won't appear in OpenOffice. I won't be holding my breath waiting for a WordPerfect filter in OpenOffice, because I gather that it is quite difficult to convert WordPerfect files to other formats.
IIRC, Win2k and recent installation generators partially avoid the DLL hell problem by
encouraging applications to install their own DLLs in their own separate installation directory. This negates many of the advantages of DLLs.
DLL hell has been a genuine problem for a considerable time (>2 years), even if you haven't seen it in Win2k in the past 2 years. Try setting up a Win95 machine and install some old software if you are feeling masochistic!

You could replace it with: (c,c,(c,(c,(c)?)?)?)
This is true to a certain extent, but the complexity of XML Schema outweighs its expressiveness.
RELAX NG seems to be a much better compromise to me. YMMV.
Yeah, but what if you add in the JVM startup time? :=)

StarOffice 6.0 does have a WordPerfect filter. I believe that it is licensed from another company, so Sun cannot migrate the filter to OpenOffice.
See this thread in a previous discussion for links to the StarOffice blurb as well as a link to a project for WordPerfect support in OpenOffice.

The language is deliberately misleading.
There is a difference between "is not designed to work" and "is designed not to work". Bah!
