OpenFormula: 5.14 White Space Clarification

["Dennis E. Hamilton" <dennis.hamilton@acm.org>]

In Document OpenDocument-formula-20080516:

Section 5.14 Whitespace, second paragraph is contradictory.

The character entity for ASCII character 10 (LF control code) is "&#0A;" and
that is indeed the normal C-Locale treatment of character literal '\n'.
(0x0D is the CR control code, '\r', ASCII code 13) 

	-	-	-	-	-	-	-	-	-

Incidental observations: 

 1. The use of C-isms, such as "(\n)" are probably inappropriate here.
Also, ASCII is not quite it.  It might be more appropriate to reference
against Unicode, using U+000A or '\u000A' and then explicitly define the
restrictions on character codes made for OpenFormula.  

 2. If the XML Specification's form of EBNF is adopted, you could create
non-terminals for these codes using that specification's notation for
literal Unicode code-points.  (I haven't checked the ISO EBNF to see if it
handles that.)

 3. space, tab, newline, and carriage return should probably be explicitly
defined, giving the corresponding codes, with some indication that there are
no other code points recognized as white space in OpenFormula formulae coded
in XML attribute values.  (This rules out some other Unicode code points
outside of the C0 Controls and Basic Latin block that constitute flavors of
white space.)

[These are incidental observations because I haven't checked everywhere in
the ODF and OpenFormula drafts to see if this is already addressed
somewhere.]
