I came across a format today which allows
fields to be fixed length or delimited on a per element basis. The delimiter
is allowed to vary on a per element basis. This indicates that the delimiter
would be naturally modelled as a terminator in DFDL, as opposed to a separator.
However, the final terminator in the document must never appear.
Not can be missing, but must be missing. This suggests that dfdl:documentFinalTerminatorCanBeMissing
is not flexible enough, and instead needs to be a 3 way property - 'yes',
'no', 'always'.
