zend_locale_data: How to add custom / own xml?

I want to add format pattern to format dial numbers as an xml file to the data directory of zend_locale_data. At the moment there are no format patterns available via CLDR,开发者_如何转开发 so i want to add it to my local zend framework environment.

As mentioned here, comment of Thomas Weidner at 26/Nov/07 2:04 AM, there is a way, but I can not find the file (file name is not written in that post) in the data directory (not in ZF 1.0.2 or in a newer one: e.g. 1.11.3).

I can not extend the Zend/Locale/Data.php and add a new case "dialnumber" to the switch-case in getContent(), because there are some private vars used (instead of protected) in getContent().

How to add a own "dialNumber.xml"?
