How to find custom attribute values in Reportable REST API output, limit output, and decode coded information

For background of my overall objective, please reference:

============================================

   https://jazz.net/forum/questions/116952/use-reportable-rest-api-to-obtain-child-work-item-attributes-based-on-parent-and-child-attributes

Specific background:

================

   In an attempt to achieve the overall objective, I am running the following statement:

      https://<server:port>/ccm/rpt/repository/workitem?fields=workitem/workItem/(id|summary|state/(name|group)|parent/*|children/*|customAttributes/*)

It gives output like the following:

Specific Questions

================

1)      How do I use the Reportable REST API to return the actual value of the custom attributes “MICSES_Source_File_CI_Name” and “MICSES_Source_file_CI_Version_dec”?

2)      Is there a way to ask the Reportable REST API to only return the fields I care about?  (id, planned for, state, parent, child, MICSES_Source_File_CI_Name, MICSES_Source_file_CI_Version_dec)  It seems that the output is providing a lot more information than that.

3)      Do I need to worry about some of the coded values (like <itemId>_xWBuR7KCEeKGFqpUni6-Kw</itemId>)?  If yes, how do I decode those?
