You cannot publish records, and this is not planned.

This is because things like

MyClass.MyRecord.MyField:=12;

do not work as one would naively expect. It does work if you use a TPersistent
instead of a record (the very reason the TPersistent class was invented)

However, you can use extended RTTI to access this typeinfo and manipulate the record. 
That works.
