A KeyStoreType represents the information needed to load a collection
of key and certificate material from a desired location.
The "url", "file", and "resource" attributes are intended to be
mutually exclusive, though this assumption is not encoded in schema.
The precedence order observed by the runtime is 
1) "file", 2) "resource", and 3) "url".

This attribute specifies the type of the keystore. 
It is highly correlated to the provider. Most common examples
are "jks" "pkcs12".

This is not the password that unlock keys within the keystore.

This attribute specifies the keystore implementation provider.
Most common examples are "SUN".

"http://..." "file:///...", etc. Only one attribute of
"url", "file", or "resource" is allowed.

This element should be a properly accessible file from the

"url", "file", or "resource" is allowed.
