Because of applying of this fix,
http://issues.ez.no/IssueView.php?Id=14328&activeItem=1

some functionality on site stopped working.
This is unacceptable to automatically apply patches that change standard behaviour of the ezpublish kernel.

Please could you make a patch that allows to override custom tag template by attribute_identifier

Steps to reproduce

Example override that worked before the patch, and now silently fails:

[factbox]
Source=content/datatype/view/ezxmltags/factbox.tpl
MatchFile=factbox_override.tpl
Subdir=templates
Match[attribute_identifier]=body
