Mike Beckerle commented on DAFFODIL-845:
----------------------------------------
lax behavior is basically not well defined by the ICU library and the
maintaners of that insist that "lax" behavior can't be pinned down (per email
threads on DFDL workgroup email list).
DFDL spec is evolving to be less specific about what "lax" means for number
parsing.
> textNumberProps: Issues with textNumberCheckPolicy="lax"
> --------------------------------------------------------
>
> Key: DAFFODIL-845
> URL: https://issues.apache.org/jira/browse/DAFFODIL-845
> Project: Daffodil
> Issue Type: Bug
> Components: ICU
> Affects Versions: s11
> Reporter: Jessie Chab
> Priority: Major
>
> According to errata item 2.21:
> 2.21. Section 13.6. Change meaning of textNumberCheckPolicy enum 'lax' to
> align with ICU.: "If ���lax' and dfdl:textNumberRep is 'standard' then
> grouping separators are ignored, leading and trailing whitespace is ignored,
> leading zeros are ignored, quoted characters may be omitted."
> I wrote two tests for the last part of that requirement, and they result in
> Parse Errors.
> see tests test_textNumberCheckPolicy_lax01, test_textNumberCheckPolicy_lax05
