560 As an embedded protocol, GIF may be part of larger application protocols,
561 within which GIF is used to render graphics. In such a case, the application
562 protocol could define a block within which the GIF Data Stream would be
563 contained. The application program would then invoke a GIF decoder upon
564 encountering a block of type GIF. This approach is recommended in favor of
566 that do not process them. Because a GIF Data Stream must be processed in
567 context, the application must rely on some means of identifying the GIF Data

1851 B. GIF Grammar.
1856 the sequence of blocks that form the GIF Data Stream. A grammar is given by
1861 symbols. The following legend defines the symbols used in this grammar for GIF.
1872 <GIF Data Stream> ::= Header <Logical Screen> <Data>* Trailer
1874 This rule defines the entity <GIF Data Stream> as follows. It must begin with a
1888 <GIF Data Stream> ::= Header <Logical Screen> <Data>* Trailer

2386 The following sequences are defined for use in mediating control between a GIF
2387 sender and GIF receiver over an interactive communications line. These
2388 sequences do not apply to applications that involve downloading of static GIF
2389 files and are not considered part of a GIF file.
2391 GIF CAPABILITIES ENQUIRY
2393 The GIF Capabilities Enquiry sequence is issued from a host and requests an
2394 interactive GIF decoder to return a response message that defines the graphics
2397 supported. The escape sequence for the GIF Capabilities Enquiry is defined as:
2401 GIF CAPABILITIES RESPONSE
2403 The GIF Capabilities Response message is returned by an interactive GIF decoder
2411 '#' GIF Capabilities Response identifier character.
