/**
* Parsed binding ID string.
*
*
* {@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.
*
*
* {@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.
*
*
* 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.
*
*
{@link BindingID} and {@link WSBinding}
*
* {@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.
