If you choose double-quotes, then double-quotes in the attribute value must be encoded as entities (named or numerical); if you choose single-quotes, then single-quotes in the attribute value must be encoded as entities. You can also encode any other character in the attribute value with an entity. An XML parser must decode all entities in attribute values. 19776-1 should conform with that, neither being more restrictive nor less.

Totally agreed.

Further, like it or not, once the scene leaves their keyboard, an author has no option to enforce one form or another since XML Recommendation allows user-agent tools to utilize whichever form they prefer for representing attribute delimiters and corresponding contained character entities.

all the best, Don
