As shown in Figure 17-1, an IF contains three primary kinds of standards:
Examples might be the kinds of XML standards, such as SAML, that we discussed in Chapter 11.

These are specific hardware choices that affect interoperability. The organization may set some hardware standards strictly as a purchasing decision. Those would not typically be included in the IF. Inclusion in the IF should be done on the basis of interoperability benefits rather than purchasing power or efficiency.
Each of these may be broken into subareas, as necessary, and in each subarea choices are enumerated and documented. In addition to sections enumerating standards, an introductory section should contain the following information:
