[sc34wg3] fundamental types

Bothered by the definition of fundamental types in the data model:
*****3.7 fundamental types******
the types of values that are so basic that they have no topic
map-defined semantics independent the context they
*****/3.7 fundamental types*****
(This language also appears at "4.2 The fundamental types" so if changed
here needs to be changed there as well.)
What caught my eye initially was the phrase: "independent of the context
they appear in" which struck me as odd, considering that the fundamental
types are string, set and null. (see 4.2 The fundamental types)
Then I thought, oh, it means that these value types never change, that
is a string is always a string, wherever it appears, etc.
Well, then why do I need the explanation that it has "no topic
For that matter, what is gained by gathering these three value types up
into a class of some sort?
Move the terms string, set and null out of 4.2 (where they are mixed
with equality tests) into the glossary.
Then, rename 4.2 to: Equality of Strings, Sets and Null
and leave the second paragraph for each term that is presently in place.
I think these are common enough to not need any defense as "fundamental"
value types and simply defining them without further explanation is
A couple of related questions on the citation of Unicode in the
defintion of string.
First, Unicode 4.0 is out so perhaps we need to change that in "2
Normative References" to: "The Unicode Consortium. The Unicode Standard,
Version 4.0.0, defined by: The Unicode Standard, Version 4.0 (Boston,
MA, Addison-Wesley, 2003. ISBN 0-321-18578-1" (odd I know but that is
the citation form given at: http://www.unicode.org/versions/Unicode4.0.0/)
Second question: The technical report for normalization (#15) is cited
in Unicode 4.0.0 but does not actually appear in the volume. Should we
make some more specific reference to the report itself?
Note that the Unicode Standard will continue to evolve so would it be
better to simply point to the Unicode website?
Hope you are having a great day!
