           Summary: [FS] technical: 2.3.1 ElementValue
           Product: XPath / XQuery / XSLT
           Version: Candidate Recommendation
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Formal Semantics

2.3.1 / -- / para 4,5,6
"Element nodes have a type annotation and contain a complex value or a
simple value. ... A simple value is a sequence of atomic values. A complex
value is a sequence of attribute nodes followed by a sequence of element,
text, comment, or processing-instruction nodes."

    First, this definition doesn't support the following example from
    2.3.2:
          element weight of type xs:integer {
            attribute xsi:type of type xs:QName {
              "xs:integer" of type xs:QName
            },
            42 of type xs:integer
          }
    (An attribute node followed by an atomic value doesn't satisfy the
    definition for 'complex value' or 'simple value'.)

    More generally, what is the mapping between FS ElementValues and XDM
    ElementNodes? In particular, if an FS ElementValue V represents an
    XDM Element Node N, then what does V's inner Value represent, with
    respect to N? It seems that sometimes it represents the concatenation
    of N's 'attributes' and 'children' properties, and sometimes it
    represents the concatenation of N's 'attributes' and 'typed-value'
    properties. (The above example is an instance of the latter.) I think
    this is non-obvious enough that it should be spelled out.
