Plural form use of the attribute, method, event, and property pragmas overwrites computed key names

[robbear]

If a source file mistakenly uses the plural form of the pragmas - attribute, method, event, property - the default case in the switch statement is invoked in the parse method. This results in a key being used that conflicts with the computed plural form of the pragma. The result is that instead of the consumer of the document seeing an Array for the pragma values, a string is returned.

Because the code converts "attribute" to "attributes", etc, the plural form used within a document source should be treated as a no-op so that the author will address the error in their documentation.
