While the term "value of a control" is used in the accessible name 
calculation, it is used elsewhere.  For example, it is referenced from 
section 5.6.2 "Widget Values" in the core-aam:

Quoting the first sentence, where the word "value" points to the current 
glossary entry (my emphasis):
"Some WAI-ARIA roles are widgets that have a particular *value* within a 
range of values."

I think we need something more general here that captures the concept of 
"value" as it is used for controls and widgets.  I suggest removing any 
text regarding names, descriptions, aria-labelledby, aria-describedby, 
etc. from your definition.  For example, how about rewording the first 
couple of sentences:

"Definition of 'Value (of a control)':

The value of an element or form control is defined by the following 
properties of the element, using the following order of precedence:

Regarding the items in the precedence, I'm not sure that the ones 
involving @alt, @title, and @aria-label play a role with respect to 
"value of a control" -- still thinking about it...
