>                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2089
>             Project: Daffodil
>          Issue Type: Bug
>          Components: Unparsing
>    Affects Versions: 2.3.0
>            Reporter: Michael Beckerle
>            Assignee: Josh Adams
>            Priority: Major
>
> When unparsing, suppose you have a sequence with an escape scheme defined, and multiple separators:
> <xs:sequence dfdl:separator="| ; ,">
> Suppose dfdl:generateEscapeBlock='whenNeeded'
> When unparsing, the sequence's children will be output using "|" separators.
> Any "|" found in the data will cause escaping (either with the escape character or by surrounding the element value with escape block.)
> The bug is this. If the data contains any of the OTHER separators, no escaping is done.
> That means the output data might contain unescaped separators.
> This will cause a subsequent re-parse of this data to interpret those unescaped separators as actual separators, which is broken.
> The escaping of the data on unparsing needs to escape not only the canonical first separator, but all separators.
