    [ https://issues.oasis-open.org/browse/WSCALENDAR-507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=41256#comment-41256 ] 

William Cox commented on WSCALENDAR-507:
----------------------------------------

Part of the exposition reflects on use of the normative reference ISO 8601, where intervals are defined with start, end, and duration, any two of which are optional.

Section 4 should be edited to reflect normative decisions, but the possible expressions in a PSM should be described - we have two PSMs that I've worked with: (1) WS-Calendar 1.0, where start-duration is the required combination, and the ASHRAE SPC201P PSM with respect to the PIM where start and end are required. The optionality and semantics are defined by a PSM, and expressing the range of possibilities seems important.

Modified to address SECTION 4 in its entirety.

> Section 4.2.1 Model Diagram reads in part: ***** The class · ToleranceValueType is comprised of a set of optional attributes of DurationType. Tolerances can be expressed in any combination; however, the complexity of rules addressing the relationships of tolerances in start, end, and duration will likely lead to implementation-specific rules limiting the concurrent uses of tolerance attributes. ***** It is difficult to tell is this is expressing a normative requirement or is it simply commentary along the way? The majority of section 4 reads this way so take this as a single example.
