The feature name is any fully-qualified URI. It is
possible for an XMLReader to recognize a feature name but
temporarily be unable to return its value.
Some feature values may be available only in specific
contexts, such as before, during, or after a parse.
Also, some feature values may not be programmatically accessible.
All XMLReaders are required to recognize the
http://xml.org/sax/features/namespaces and the
http://xml.org/sax/features/namespace-prefixes feature names.
Implementors are free (and encouraged) to invent their own features, using names built on their own URIs.
Parameter:
name: feature name, which is a fully-qualified URI.Returns:
The current value of the feature.
