| "required" |
Most steps in a procedure
are sequential: do the first, then the second, then the third. Sometimes
procedures provide an explicit ordering: do step 7 next.
The stepalternatives element was added to
support the semantics of alternative steps: perform exactly one of the
following steps. The reader is presumably given some criteria for deciding
which one to choose, but the significant difference is that only one of
the steps is performed.
Performance specifies whether one
of the step alternatives must be performed or if the whole
set is optional. (In no case is more than one alternative performed.)
