Management of tags embedded in a data stream is provided by a shell structure resource. Formatting directives and routines for processing the data stream are specified in the shell. Sometimes, multiple shell structures, including shells redefined by applying modifications specified by a second shell structure or by a shell structure fragment, are required to be accessed by the data stream process. The default shell structure, as well as any redefined shell structure, are identified by a structured field that maps the name of the shell structure to a coded identifier. To satisfy the requirement that resources be activated before being accessed necessitates that both identification and activation of a shell structure controls be included in the data stream.
