decision re optional Expr in braces

The minutes say:

> DECISION: WG has agreed to refactor the grammar using the EnclosedExpr in

*Computed* node constructors, that is.

The same reasoning would apply to any 'name expression', i.e. also in
CompAttrConstructor and CompPIConstructor.

> Consider the expressions Try, Catch, Validate, ExtensionExpr, Ordered and
> Unordered, CompDocConstructor, CompAttrConstructor, CompTextConstructor,
> CompCommentConstructor CompPIConstructor and Namespace

[Note that this sentence appears in the body of the minutes, but not in the
collected decisions section at the top.]

The WG decided to *consider* these expressions? What does that mean? I can
imagine it meaning "the WG decided to consider these expression at some
later time", or "this action item should be taken as applying to these
expressions", but either way, it conflicts with the first sentence of the
action item, which refers to "node constructors". Please clarify.

Also, presumably "Namespace" should be "CompNamespaceConstructor"?
