Existing Wording: If there is more than one type, the element offers a choice of types and must have a name that terminates in "[x]". When profiling a resource and only one type is specified, the name of the element is changed to include the type instead of '[x]'.

Proposed Wording: add: When substituting [x] with a specific data type, always capitalize the first letter of the data type regardless of what the "Data Types" page shows. Choice types are always camel-case. Ex: "effectiveDateTime" is correct, "effectivedateTime" is NOT correct.

Comment:

This statement should be moved to its own bullet-point. Suggesting the addition of "proposed wording" to this bullet point.

Summary:

Explain capitalization when substituting for [x]
