I am parsing One Note documents.
When I find property IDs from within the OneNote documents, I find most of them in the OpenSpecs document: https://docs.microsoft.com/en-us/openspecs/office_file_formats/ms-one/e9bf7da8-7aab-4668-be5e-e0c421...
But there are quite a few that seem to appear in OneNote files that I do not see in the Spec:
0x14001c9e
0x14001c9f
0x14001ca0
0x14001ca1
0x14001df9
0x1400348b
0x1c001d61
0x1c001df8
0x1c001dfb
0x1c001dfc
0x1c001e30
0x1c0035b7
0x88001c8e
0x88001cbd
0x88001cdc
0x88001d13
0x88003462
Where do I find information about these properties?
