ZF-4051: XML context for ContextSwitch uses deprecated Content-Type header

Description

The default XML context used by the ContextSwitch action helper sets the Content-Type header to a value of text/xml, which is being deprecated in favor of application/xml. This change is already visible in applications such as Firefox 3. See http://lists.xml.org/archives/xml-dev/… for more details.

Comments

Added a patch file that modifies the Content-Type header value being set in the ContextSwitch action helper class file as per the issue description.

Scheduling for RC3

Fixed in trunk and 1.6 release branch

Updating for the 1.6.0 release.
