/**
* XTee messages are sometimes allowed to contain MIME attachments, which this class encapsulates. Each attachment has
* MIME content-type, data (content) and unique ID. This class implements {@link InputStreamSource} for a nice fit into
* Spring-WS and provides easy access to attachment content. Attachments are the preferred way of transporting large
* amounts of data because transmitting attachments requires much less bandwidth and resources (base64 etc) than
* transmitting the same data within SOAP messages without attachments.
