This seems to be a documentation bug, more than anything. The Grammatica RE:s support unicode character references in the following way:

\uFFFF (where FFFF is the Unicode hexadecimal code)

So the example above would be expressed in the following way (untested):

Char = <<\x09|\x0A|\x0D|[\u0020-\uD7FF]|[\uE000-\uFFFD]>>

Note the use of \x for two-character hexadecimal encoding and \u for four-character encoding. Also note that the character sequence [#x10000-#x10FFFF] has been omitted, see bug #7916 for more information.

BTW, I submitted it (dcazzulino, that is).

One consequence of not using SDK built-in regular expression support is that unicode support is not available. For example, the XML grammar defines Char as follows:

Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]

How could that be expressed with grammatica? If it supported built-in regex engine, this would be no problem (in .NET at least :o)

BTW: I'm seeking for an XML/RelaxNG parser.
