/**
* The MultipartAttachmentStreams class is used to create IncomingAttachmentInputStream objects when
* the HTTP stream shows a marked separation between the SOAP and each attachment parts. Unlike the
* DIME version, this class will use the BoundaryDelimitedStream to parse data in the SwA format.
* Another difference between the two is that the MultipartAttachmentStreams class must also provide
* a way to hold attachment parts parsed prior to where the SOAP part appears in the HTTP stream
* (i.e. the root part of the multipart-related message). Our DIME counterpart didn't have to worry
* about this since the SOAP part is guaranteed to be the first in the stream. But since SwA has no
* such guarantee, we must fall back to caching these first parts. Afterwards, we can stream the
* rest of the attachments that are after the SOAP part of the request message.
