Secure XML: The New Syntax for Signatures and Encryption

The current online home page for FIPS is

http://www.itl.nist.gov/fipspubs/

The government's level of commitment to the stability of this URL or those of particular FIPS documents remains unclear. On occasion we have found broken links within the NIST Web site. If you run into this problem, just try other paths through the Web page hierarchy to get what you want.

FIPS are also generally publicly available as printed documents through the U.S. Government Printing Office [GPO].
