Description
The new syntax map{a "b"} is recognized as an ExprSingle, not as a Primary. This means it cannot be used in some contexts, for example
map{} instance of map(*)
Also, Saxon recognizes map expressions in the form {a (without the "map" keyword), which was a syntax at one time proposed by the W3C working groups, but subsequently dropped.
A patch is being committed on the 9.6 and 9.7 branches to recognize map expressions only as a Primary, and to drop support for the "bare curly braces" syntax, which can lead to confusing error messages.
