I agree with Detlev and Makoto about separating SC 2.5.3 from 1.1.1.

My understanding of the rational for merging 1.4.5 into 1.1.1, is that 1.1.1 contains a few instances that dictate what the text alternative must be (e.g., null alt, alt==name) but not a complete list.  Having the alt attribute value be the words from an image of text is something that could have been explicitly included in 1.1.1.

This gets at what I was trying to say on the call yesterday, that 1.1.1 divides its use cases into "textual equivalent" and "descriptive identification".  I think the Silver version of 1.1.1 might group null alt, alt==name, and alt==words-from-an-image-of-text all as examples of textual equivalents.

I think 2.5.3 Label in Name  covers a very distinct aspect (matching visible label to accName) that should be kept separate from 2.4.6 where the point is to check whether label /heading texts are appropriate / descriptive of content or function - a semantic, not programmatic match. So I would recommend *not* to merge these two.
