Reference is at http://icu-project.org/apiref/icu4j/com/ibm/icu/text/DecimalFormat.html#setParseStrict-boolean-
and gives an example where using a + in the data but not the pattern gives
an error when strict. The implication would be that this is not an error
when lax, but testing with IBM DFDL does not bear this out. IBM DFDL behaviour
matches the DFDL spec. Looking at our code, we do some pre-processing before
passing data & pattern to ICU, but not plus sign checking, so it's
ICU behaviour.

I'm pretty sure I've hit this with EDIFACT
in the past. A particular field had an explicit sign and needed to be modelled
with a pattern that included the sign.
Having said that, having a field that sometimes
included a + and sometimes didn't feels like it should be a common occurrence

Subject:
[DFDL-WG] clarification
needed: textNumberCheckPolicy lax includes lax-ness about plus signs.
Sent by:
"dfdl-wg"
<dfdl-wg-bounces@ogf.org>
Excerpt from daffodil users mailing list
indicates that the discussion of how "lax" textNumberCheckPolicy="lax"
is w.r.t. plus signs on numbers.
> If you set textNumberCheckPolicy="lax",
then
> we do ignore leading plus signs
in the data
The DFDL specification doesn't seem
to say that a leading plus sign is ignored. Here's what it says:
If 'lax' and dfdl:textNumberRep is 'standard'
then grouping separators are ignored, leading and trailing whitespace
is ignored, leading zeros are ignored and quoted characters may be omitted.
Nothing about ignoring plus signs in
that.
