As an instance of the SAYAS tag, consider the rendering of the date
``4/5/98'' via the U.S. versus non-U.S. methods. These two ways of
expanding the string can be specified as:
<SAYAS MODE="date" MODETYPE="MDY">4/5/98</SAYAS>
<SAYAS MODE="date" MODETYPE="DMY">4/5/98</SAYAS>
respectively. Specifications of this kind are unavailable in other inline markup schemes (e.g. SAPI), but they are useful since they have the potential to reduce cross-synthesizer inconsistencies. That is, without SAYAS specifications of the kind specified above, one cannot control whether a new system will pronounce ``4/5/98'' as ``April 5, 1998'' or ``May 4, 1998''. The behavior for SABLE-compliant engines is, however, guaranteed.
