>                 URL: https://issues.apache.org/jira/browse/JENA-2008
>             Project: Apache Jena
>          Issue Type: Improvement
>          Components: SHACL
>    Affects Versions: Jena 3.17.0
>            Reporter: Andy Seaborne
>            Priority: Minor

> SHACLC parsing
> {noformat}
> shape ex:shape2 {
>  targetNode = :WhatEver .
>  ex:A|ex:B|ex:C datatype=xsd:integer .
> }
> {noformat}
> produces
> {noformat}
> sh:path [ sh:alternativePath ( [ sh:alternativePath ( ex:A ex:B ) ] ex:C  )
> {noformat}
> which evaluates correctly but it could be {{sh:alternativePath ( ex:A ex:B ex:C  )}}.
> Printing SHACLC (and SPARQL) paths ({{PathWriter}}) puts in {{()}} over-cautiously to get {{(ex:A|ex:B)|ex:C}}.
