Comment title: Full Range of Unicode Code Points Not Allowed in XML
Comment:
--------------------------------------------------------------------------
"[S] Specifications SHOULD allow the use of the full range of Unicode code points from U+0000 to U+10FFFF inclusive; code points above U+10FFFF MUST NOT be used."
--------------------------------------------------------------------------
CONCERN:
If this is truly a goal for text on the Web, users should understand why XML is unable to achieve this.  As a high profile W3C spec, readers are likely to notice the inconsistent message.  Does this mean that I18N believes that XML (1.1 or some later version) should support the characters 0x0-0x1F?

RECOMMENDATION:
If XML 1.1 is unable to achieve this goal, the Character Model spec should either remove this requirement or explain the discrepancy.
