 /**

  * Parsed binding ID string.

  *

  * <p>

  * {@link BindingID} is an immutable object that represents a binding ID,

  * much like how {@link URL} is a representation of an URL.

  * Like {@link URL}, this class offers a bunch of methods that let you

  * query various traits/properties of a binding ID.

  *

  * <p>

  * {@link BindingID} is extensible; one can plug in a parser from

  * {@link String} to {@link BindingID} to interpret binding IDs that

  * the JAX-WS RI does no a-priori knowledge of.

  * Technologies such as Tango uses this to make the JAX-WS RI understand

  * binding IDs defined in their world.

  *

  * Such technologies are free to extend this class and expose more characterstics.

  *

  * <p>

  * Even though this class defines a few well known constants, {@link BindingID}

  * instances do not necessarily have singleton semantics. Use {@link #equals(Object)}

  * for the comparison.

  *

  * <h3>{@link BindingID} and {@link WSBinding}</h3>

  * <p>

  * {@link WSBinding} is mutable and represents a particular "use" of a {@link BindingID}.

  * As such, it has state like a list of {@link Handler}s, which are inherently local

  * to a particular usage. For example, if you have two proxies, you need two instances.

  *

  * {@link BindingID}, OTOH, is immutable and thus the single instance

  * that represents "SOAP1.2/HTTP" can be shared and reused by all proxies in the same VM.
