I believe one of our engineers spotted a bug in the spec. See below.

Subject: XML 1.1:  NameStartChar not a subset of Char?

Hi folks.  This looks like an erratum to me, but I could be wrong:
production [2] of 1.1 states, in part:

[2] Char ::= ... | [#xE000-#xFFFD] | [#x10000-#x10FFFF]

But [4] states:

[4] NameStartChar ::= ... | [#xF900-#xEFFFF]

So 0xFFFE and 0xFFFF are NameStartChars but not Chars?

If I'm not wrong, let me know if you want me to send a note to
www-xml-blueberry-comments@w3.org or if this is best left up to one of our
