Details

One might to use different parsers to test validity of a document in different ways and to get different error messages. Additionally, one parser may be more efficient than the other. These methods allow one to write code in such a way that one parser is preferred and is used if it is available, but the other is used if the first is not available.

Value

Returns TRUE if the corresponding library has been linked into the package.
