Relationship between alt text and desc elements

Hi folks,

I'm looking for thoughts on a concrete problem:

The context is an acyclic directed graph diagram in a specification.  
Translating to "common jargon", it looks like a flowchart.

I've made an SVG available at  
https://lists.w3.org/Archives/Public/w3c-wai-ig/2021JulSep/att-0145/credential-graph.svg

It includes a <desc> element laying out the pieces. It uses text elements  
for all the labels. If you read through sequentially it is various named  
containers that each list several labels followed by their value.

To include it in an img element, I *think* it makes sense to write an alt  
attribute that describes the core pieces in general terms, rather than the  
complete detail, because it is an example anyway. I have taken the same  
approach with the desc element in the SVG itself.

The sort of difference I am asking about is between on the one hand

"The Signature has a type, of 'RsaSignature', an issuance date of 3  
november, a creator of 'example university public key 11', a signature of  
'aeunvaeournvq[e8nv', and a nonce of 123abcfeed321".

or on the other hand

"A signature with a nonce, date, algorithm used and a public key for the  
proof's creator".


cheers
