Defines
and
enforces
the
minimum
expectations
for
publication
and
distribution
of
a
value
set,
typically
as
part
of
an
artifact
repository
or
implementation
guide
publication
Defines
a
computable
value
set
as
one
that
SHALL
have
an
expression-based
definition
(i.e.
a
value
set
defined
intensionally
using
expressions
of
the
code
systems
involved)
and
MAY
have
an
expansion
included.
The
expression-based
definition
SHALL
be
represented
in
only
one
of
three
ways;
using
the
compose
element,
using
the
expression
extension,
or
using
the
rules-text
extension
to
provide
a
step-by-step
process
for
expanding
the
value
set
definition
Defines
an
executable
value
set
as
one
that
SHALL
have
an
expansion
included,
as
well
as
a
usage
warning
indicating
the
expansion
is
a
point-in-time
snapshot
and
must
be
maintained
over
time
for
production
usage.
The
value
set
expansion
specifies
the
timestamp
when
the
expansion
was
produced,
SHOULD
contain
the
parameters
used
for
the
expansion,
and
SHALL
contain
the
codes
that
are
obtained
by
evaluating
the
value
set
definition.
If
this
is
ONLY
an
executable
value
set,
a
computable
definition
of
the
value
set
must
be
obtained
to
compute
the
updated
expansion.
