[jira] Resolved: (UIMA-387) XMI Serializer can write invalid control characters

["Adam Lally (JIRA)" <ui...@incubator.apache.org>]

     [ https://issues.apache.org/jira/browse/UIMA-387?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adam Lally resolved UIMA-387.
-----------------------------

    Resolution: Fixed
      Assignee: Thilo Goetz  (was: Adam Lally)

Moved the check to the XMLSerializer class and enhanced it to allow through XML 1.1 characters when the output format is set to 1.1.

Thilo go ahead and close if you are satisified (or if you don't care :)
