wd15 core spec comments

["Tyson, Paul H" <PTyson@bellhelicopter.textron.com>]

Section 1.3 

	* Correct namespace reference (refers to wd-13)

Section 1.4

	* [LDAP-1] reference and hyperlink should point to
"...rfc2256.txt" (now "...rfc2798.txt")

	* [MathML] remove or update date in citation because date of
hyperlinked document is 21 October 2003.

	* [RBAC] hyperlink does not lead to link to referenced paper.
NIST RBAC site is now
http://csrc.nist.gov/groups/SNS/rbac/standards.html, but I didn't find
Ferraiolo & Kuhn paper there.

	* [RegEx] schema primer is now at 2nd edition, dated 28 October
2004.

	* [XACMLv1.0] and [XACMLv1.1] hyperlinks lead to members-only
links on oasis site.  Is that intended?

Section 2.3

	* Next-to-last paragraph: change "behaviour" to "behavior".

Section 3.3.2

	* Delete 3.3.2.1 and 3.3.2.3 (these are duplicated in 3.3.2.5
and 3.3.2.6).  Remaining 3.3.2 subsections will be renumbered.  Change
title of current 3.3.2.5 from "Obligation expressions" to "Obligations".

Section 3.3.3.2

	* In first sentence, change "obligations expressions" to
"obligation expressions".

Section 5.30

	I suggest moving most of this material to section 7.3, Attribute
Evaluation.  I will post proposed rewrites to sections 5.30 and 7.3 in a
separate email.

Section 5.42

	* 2nd paragraph: "...if the PDP implements multiple resources
profile..." should be "...multiple decision request profile..."
	
	* 2nd paragraph: Delete last two sentences, starting with "Each
child element...".  These add nothing to the discussion of the <Request>
element.

Section 7.17

	* 1st paragraph: change "behaviour" to "behavior".

Section B.4

	* 3rd paragraph: missing reference at end of last sentence.

Section B.5

	* 2nd paragraph: remove 2nd sentence, which describes use of
resource-id to select XML content.
