(Reason:
This
element
is
labeled
as
a
modifier
because
it
is
a
status
element
that
contains
status
entered-in-error
which
means
that
the
resource
should
not
be
treated
as
valid)
This
is
intended
to
deal
with
the
confusion
routinely
created
by
haing
two
conflated
concepts
of
being
in
a
particular
state
and
having
achieved
a
particular
milestone.
In
strict
terms
a
milestone
is
a
point
of
time
event
that
results
in
a
change
from
one
state
to
another.
The
state
before
the
milestone
is
achieved
is
often
given
the
same
name
as
the
milestone,
and
sometimes
the
state
may
have
the
same
description.
For
instance
"Randomised"
and
"Visit
1"
may
be
different
milestones
but
the
state
remains
at
"on
study"
after
each
of
them.
It
is
likely
that
more
than
one
"state"
pattern
will
be
recorded
for
a
subject
and
a
type
has
been
introduced
to
allow
this
simultaneous
recording.
