[jira] [Commented] (DAFFODIL-2346) XML Output needs option to use around simple element values containing whitespace.

["Steve Lawrence (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DAFFODIL-2346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17642122#comment-17642122 ] 

Steve Lawrence commented on DAFFODIL-2346:
------------------------------------------

Note, I'm not sure using a tunable is the right approach here. Tunable have mainly been used for changing Daffodil parse/unparse behavior, and not infoset inputter/outputter behavior. And right now, there really isn't a good way to get tunables to the infoset inputter/outputters since those are created by users and not part of the compiler/data processor where tunables live.

So I think InfosetInputters/Outputters want to be configured by constructor parameters (or public setter functions if we're okay with mutability). I suggest we just make the pretty print safe option a constructor parameter that is currently only available to API users. And I suggest create another bug to figure out the right CLI mechanism to pass infoset inputter/outputter specific properties to these constructors, which a number of other bugs need.

> It is incredibly painful to take the XML output, pretty print it to make it readable, and find out that this has mangled the significant whitespace inside element values. 
> In general, since whitespace within simple values is considered fungible in XML, we have to protect whitespace that is truly part of the DFDL infoset. 
> I think CDATA bracketing is preferable to replacing whitespace characters with XML escaping like &amp;#x20;
