From 8a6fdadccd2eedf332ae3a72f0149c1b40cb5bd9 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Tue, 9 May 2017 15:03:33 -0700 Subject: Create common CXML_Object base class for CXML_Content and CXML_Element. They should each know what they are rather than having an external ChildRecord struct to track the type.
