Yes Usability being related to many aspects of the technology which  
goes as far as
     - understanding the technology
     - being able to make sense of the conformance model
     - being able to navigate the set of documents

If it's in ViS, it should be in the conclusion or in the introduction  
as a way to reduce variability introduce by the fragmentation of the  
technology among many documents.

Variability is introduced because of technology fragmentations. When  
the document is monolithic. The package is obvious to the developer  
(or at least should be). When you  introduce many documents  
(editorial fragmentation), you somehow introduce a new variability  
which might have side effects on usability (understanding,  
conformance, etc.)

* Some search on the Web

has adopted the “Umbrella Specification” or “U-Spec” as standard for  
the declaration of its product material content. Infineon provides  
the Umbrella Specification as an efficient means to providing our  
customers with detailed information, based on an intelligent grouping  
of all products in similar packages under one "umbrella".

What is an Umbrella Specification (U-Spec)?

A “U-Spec” is a product material declaration sheet provided in an  
easy to read format, so that more than one product is reported with  
one set of data. Based on their package family or type, comparable  
products are grouped under one "umbrella" and declared with one set  
of data. This saves, time, effort and most of all makes it easier for  
our customers to manage. The U-Spec is well suited to declaring  
materials data for all semiconductor products and is already an  
industry accepted standard.

7.1.3 Architecture
The H.323 recommendation is often called an `umbrella specification'.  
This is because it uses several other ITU-T recommendations to  
provide its functionality. The structure of the H.323 architecture is  
illustrated in figure 7.1.
