So, if XML disallows certain symbols, but each Turing machine has it's
own alphabet, just because XML doesn't allow 0x0000 doesn't mean that an
XSLT stylesheet can't be a UTM, just that it has a different alphabet
from another UTM. In fact, the other page -
http://www.unidex.com/turing/utm.htm - states that: The Universal Turing
Machine stylesheet runs the Turing machine that is SPECIFIED BY THE
SOURCE DOCUMENT. 

Not some pie in the sky non-XML compliant other source document. A
Turing Machine has its own set of rules that it has to follow to get to
where it's going.

Hi,

    Found this on the web :

http://www.unidex.com/turing/utm.htm

    It seems to me that one of the implicit assumptions used by a UTM
is that it is able to write any specified symbol. If I read the XML
spec correctly though, certain symbols are not legal (for example
0x0000 is not a valid Unicode codepoint). That being the case, can
this UTM really be valid?

Thanks,
Kenneth
