Fields: Standard , Core , TiddlyWebAdaptor

[S. S.]

The tiddler: TiddlerFields shows 3 types of fields
Standard (10)
Core (18)
TiddlyWebAdaptor (2)
Total 30 fields

The control panel lists all [all[tiddlers]] fields in: $:/core/ui/ControlPanel/TiddlerFields which is a tranclusion of $:/snippets/allfields
The class & hide-body fields appears to be the only Shadow tiddler field that do not show up on this control panel list of fields.
The hack-to-give-us-something-to-compare-against field is the only field that has a description but is not a non-custom field.

The descriptions of each of these non-custom (Standard/Core/TiddlyWebAdaptor) fields are kept in tiddlers listed by: <<list-links "[all[shadows]prefix[$:/language/Docs/Fields/]]">>
The hide-body field's description is missing for now but will be added in 5.1.20
The class field's description is missing and I have no idea what it is used for.


Is there a place within the core tiddlers where non-custom fields have been designated this 3 tier category?
Are there further sub-categories?
Can this information be accessed?

Thanks.

Perhaps I can word the question differently.

I want to make a drop down list of all field names used in the TW. The list should exclude all Standard/Core/TiddlyWebAdaptor field names. Is there a place within my TW where I can find a list of these fields to exclude?

Thanks
