+
+Content types (complex) should create constant pool data
+in the recording.
+Currently at least, there is _NO_ verification that whatever
+writer you have is actually writing correctly. So BE CAREFUL!
+
+Declared with the 'content_type' tag.
+
+<type> is the ID type, i.e the integer type that resolves this. Most often
+U4 or U8, but for example really small number constants, like GCTYPE uses U1.
+
+<content-type> is where it gets interesting. 'builtin_type' means we're
+defining how we resolve one of the trace built-in types (Class, Thread etc),
+jvm_type means defining a new one for our own use.
+
+Example: (GcMode)
+
+<content_type id="GCMode" hr_name="GC mode" type="U1" jvm_type="GCMODE">
+  <value type="UTF8" field="desc" description="Description"/>
+</content_type>
+
+This creates a content type CONTENT_TYPE_GCMODE
+The field type referencing it is u1 (U1), and the constant pool struct has one field, the name.
+
+Before we can use it we need also define a primary field data type:
+
+<primary_type symbol="GCMODE" datatype="U1" contenttype="NONE"
+              type="u8" sizeop="sizeof(u1)"/>
+
+Now we can use the content + data type in declaring event fields.
+Remember however, that for us to be able to resolve the value later we must also add
+creating the constant pool data in  VM_JFRCheckpoint::write_checkpoint
+
+   ...
+   //CGMODE
+   w->be_uint(CONTENT_TYPE_GCMODE);
+   w->be_uint(MM_GC_MODE_UNINITIALIZED);
+   for (i = 0; i < MM_GC_MODE_UNINITIALIZED; i++) {
+      w->uchar(i);
+      w->write_utf8(gcModeGetName(i));
+   }
