[jira] [Updated] (DAFFODIL-1782) DFDL Extension: Enum and Range
table lookups
[ https://issues.apache.org/jira/browse/DAFFODIL-1782?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Beckerle updated DAFFODIL-1782:
---------------------------------------
Description:
Some schemas have large simple type unions that combine enumerations with many members, and numeric ranges.
Translation between numeric values, and symbolic values (strings), is desirable.
A proposal for how to do this is:
[https://cwiki.apache.org/confluence/display/DAFFODIL/Proposal%3A+Features+to+Support+Table-Lookup]
(This one is now obsolete:
[https://opensource.ncsa.illinois.edu/confluence/display/DFDL/Enumerations+and+Range+Tables+via+Simple+Type+Unions])
��
Under review by the DFDL Workgroup, it was observed that these features require validation processing, and that was considered problematic given that validation is an optional feature of DFDL.�� However, the dfdl:checkConstraints function is not optional - excepting that the whole expression language is optional. So it is reasonable to add these features to an implementation that has either validation or dfdl:checkConstraints().
