ISSUE-123: PN_CHARS_BASE permits up to U+EFFFF but RFC-3987 stops at U+EFFFD

localName chars

PN_CHARS_BASE permits up to U+EFFFF but RFC-3987 stops at U+EFFFD

State:
CLOSED
Product:
RDF Turtle
Raised by:
Eric Prud'hommeaux
Opened on:
2013-03-24
Description:
Gregg Kellogg pointed out in http://www.w3.org/mid/49EB390E-BCA6-401B-98EC-F4DD6A44AD0B@greggkellogg.net that Turtle's localNames overrun RFC-3987 iri by two characters. These two Unicode characters are reserved for process-internal use and thusly don't make sense in a global identification scheme.

Should we shave PN_CHARS_BASE down to [#x10000-#xEFFFF]? If this is a bug fix, can we do that without another LC?

Related notes:

As discussed here, I'm satisfied with the resolution. It could perhaps go in the errata, but the fact that we already normatively reference RFC-3987 makes the meaning unambiguous.
