* This interface encapsulates an arbitrary block to be used
* by the soap serialization or protocol. It presents the
* namespaceURI, name, encoding, schemaType, and value of the
* block. There are two different ways this may be used:
* <p>1. When created by a user for serialization, a value is set
* which is then used to encode the message. In this case, the
* user sets the value (or element in the case of a literal
* block) which is then encoded (unless it is the element)
* and incorporated into the document as it is encoded.
* <p>2. When requested by the user from a message that is to
* be decoded. In this case, an element is set on the block
* which is automatically decoded whenever the value attribute is
* accessed (possibly after the user sets the encoding or schemaType,
* or for literal blocks, the user just accesses the element and
* no decoding is performed. For SOAP which attachments, hidden
* attachments may also be associated from the message to the block
* so that later decoding which relies on the attachments is possible.
