The official rules for applying the ARIA naming & description calculation to SVG elements is in the SVG AAM: https://w3c.github.io/svg-aam/#mapping_additional_nd That text hasn't been updated since the Accessible Name and Description Computation 1.1 <https://www.w3.org/TR/accname-1.1/> spec was finalized as a W3C Recommendation. Please file issues on SVG AAM <https://github.com/w3c/svg-aam/issues/> if you notice any problems, or if you find the spec text confusing. (It's written as a series of patches to the ACCName algorithm, which makes it difficult to read on its own, but easier to find what is unique.) For your other questions about validity of unnamed elements, please also file issues on the spec <https://github.com/w3c/svg-aam/issues/>. I'm sorry it's been languishing so long as a working draft, but it will definitely help move it along to get some feedback from implementers & from people working on accessibility validation in real, complex websites.
