Description Patrick Durusau 2015-03-23 00:44:32 UTC 
2.2.1 Data Model Generation

list item 2 "The Information Set or PSVI may be transformed into an XDM instance by a process described in [XQuery and XPath Data Model (XDM) 3.1]. (See DM2 in Fig. 1.)"

As a point of information, XDM instance is defined in XPath 3.1 but isn't used in XDM 3.1. Not an error per se but certainly an odd read.
Comment 1 Jonathan Robie 2015-07-10 22:10:29 UTC 
XPath and F&O both use this ... it looks like something that should be defined in the XDM.
Comment 2 Michael Kay 2015-07-15 15:32:03 UTC 
Noted that XDM uses and defines the term "instance of the data model" with the same meaning as the term "XDM instance" as used in the XP3.1, XQ3.1, and F+O3.1 specs. All the specs are internally consistent and use terminology that is unambiguous and is defined within the relevant spec. It's not unreasonable for XDM to avoid using a term that is self-referential.

Decided to make no change.
