In http://wiki.civicrm.org/confluence/display/CRMDOC/CiviCase+Configuration the rule is:

   The file names should match the case type name with spaces removed and the first letter of each word upper-cased.
EXAMPLE: Case type = "Housing Support" Filename = "HousingSupport.xml"
Use a copy of one of the sample configuration files that are included in the 2.2 distribution as a starting point - and edit it to meet your requirements.
<civicrm_root>/CRM/Case/xml/configuration.sample/HousingSupport.xml

Small point but I have the following combination which works:

name: 2a RES. CARE Choosing
filename: 2aRESCAREChoosing.xml

You can see the dot is allowed (but not in the filename) and capitals after the initial capital is allowed. And numerics seem to be OK in the filename.
