===Flexible buffer formats===
Tuxedo applications can utilize a variety of message formats depending upon the type of data that is to be passed.  One of the most popular formats is the FML buffer format which is much like a binary [[XML]] or ASN.1 format.  FML buffers can contain an arbitrary number of named fields of arbitrary type.  Fields can be repeated and nested.  As it is a self-describing binary format, the processing of fields incurs very little overhead in comparison to the parsing necessary to support something like XML.  VIEW buffers are essentially records, C structures, or COBOL copybooks.  A VIEW buffer has an external description which allows Tuxedo to access the fields within it if necessary for things like data dependent routing.  Other buffer formats include XML, CARRAY (opaque binary data), STRING, and MBSTRING (a string buffer containing multibyte characters.)  Tuxedo can automatically and transparently convert FML buffers to and from XML buffers.

There is also support for user-developed buffer types (for example JamFlex buffers defined by Tuxedo version of Panther [[Rapid application development|RAD]] toolset).
