+Module Name:
+
+ SectionExtraction.c
+
+Abstract:
+
+ Section Extraction Protocol implementation.
+
+ Stream database is implemented as a linked list of section streams,
+ where each stream contains a linked list of children, which may be leaves or
+ encapsulations.
+
+ Children that are encapsulations generate new stream entries
+ when they are created. Streams can also be created by calls to
+ SEP->OpenSectionStream().
+
+ The database is only created far enough to return the requested data from
+ any given stream, or to determine that the requested data is not found.
+
+ If a GUIDed encapsulation is encountered, there are three possiblilites.
+
+ 1) A support protocol is found, in which the stream is simply processed with
+ the support protocol.
+
+ 2) A support protocol is not found, but the data is available to be read
+ without processing. In this case, the database is built up through the
+ recursions to return the data, and a RPN event is set that will enable
+ the stream in question to be refreshed if and when the required section
+ extraction protocol is published.This insures the AuthenticationStatus
+ does not become stale in the cache.
+
+ 3) A support protocol is not found, and the data is not available to be read
+ without it. This results in EFI_PROTOCOL_ERROR.
