stepalternatives
stepalternatives — Alternative steps in a procedure.
Synopsis
stepalternatives ::=
Attributes
Common attributes and common linking attributes.
Additional attributes:
- performance (enumeration)
- “optional”
- “required”
Description
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.
