Major 1. Introduction reads: ***** All text is normative unless otherwise labeled. ***** Is there any non-normative text before Section 5, which is labeled as non-normative? I ask because Section 4 (just an example, not the only one) begins: ***** In this section we introduce the PIM, and treat in turn each component of the PIM. Each subsection has an introduction, a diagram, and discussion that may include the relationship of the respective components to the rest of the PIM. This Platform-Independent Model (PIM) [MDA] describes an abstraction from which the Platform-Specific Model (PSM) of [WS-Calendar] can be derived. The intent is twofold: (1) To define an abstraction for calendar and schedule more in the style of web services descriptions, which may be used directly, and (2) To define the PIM as a model allowing easy transformation or adaptation between systems using the family of WS-Calendar specifications (such as [WS-Calendar], [xCal], [iCalendar]) as well as those addressing concepts of time intervals and Sequences (such as [IEC CIM], [EnergyInteroperation], and [EMIX]. ***** I don't experience that portion of section 4 as normative text. There are simply introductions and asides that appear to be non-normative.
