Just to amplify your point a little for the uninitiated, the current 5.3 version of the Bluetooth Core Specification is a 3085 page PDF document. That document contains Volumes 0 to 7. Each volume has multiple Parts, labelled A, B, C, ... in several cased up to Part H. And each Part has Sections with the standard hierarchical outline numbering, Section 1, Section 1.1, Section 1.1.1 etc. Each Part of each Volume can have it's own section 1.1 or 3.1 or whatever. Consequently the document contains literally dozens of Sections with the same outline number. It's extremely tedious to navigate or to find specific details (you need to guess the terminology and in some cases the terms vary from Volume to Volume).
