The following items under Normative References need changes as indicated.

(a) RFC5545 - at most informative. The normative reference to WS-Calendar includes RFC5545.

(b) SOA-RA - this should be the SOA Reference MODEL, not the Reference ARCHITECTURE.

(c) Stoft - Should be Informative. Move to section 1.4

(d) WS-Calendar - should be current WD19 (or PR02 as soon as it's published)

(e) XML Schema - this is Part 2; consider whether Parts 1 and 2 should be the references.

(f) XPOINTER is not used in the specification; delete it.
