Joe Witt commented on NIFI-6498:
--------------------------------
just needs review traction and once we have that we can set a fix version.
Patches offered this way are tougher than PRs through github as it requires
higher reviewer effort.

> When something is wrong with the XSLT in the XMLTransform processor you get
> an error, but this is only a general error without any details or the line
> number where the parsing error occurs. For example when using Saxon from
> example I get the following error:
> Error on line 17 column 5 SXXP0003: Error reported by XML parser: The element
> type "xsl:tomplate" must be terminated by the matching end-tag
> "</xsl:tomplate>".
> When using NiFi the following error is printed:
