SECTION 2: Basics First sentence: "... the expression, which is a sequence of Unicode characters." Certainly in order to support XML, an implementation will need to support Unicode in its data values, but is this necessary in a source language expression? SQL (ISO/IEC 9075) distinguishes what it calls "the source language character set", which is not necessarily the same as any character set in the data. Of course, XQuery expressions can include literals for Unicode strings, and XQueryX, being expressed in XML, is necessarily expressed in Unicode as well. But wouldn't it be sufficient for XQuery to allow the source language character set to be any implementation-defined character set, provided there was an implementation-defined mapping to convert the source language into Unicode? For example, if a user is working in an environment with EBCDIC or Shift-JIS editors, the user will probably want to compose his XQuery expressions in those character sets. - Steve B.
