Maybe we should name this "create and append an attribute"? Or maybe I don't understand "by value".
The other thing I'm thinking is that it would be nice if https://dom.spec.whatwg.org/#concept-element-attributes-set-value could invoke this algorithm as well. That would require additional arguments for namespace/prefix, but seems doable.

"validate and get an attribute by name" perhaps?

whatwg/html#3779
As I understand it vars are not mutable and are instead copied, right? This mean I still have to copy from
"get an attribute by name"the code.Would there be a way to simplify this further perhaps? I could copy out the two common steps in the body of
"get an attribute by name"and"get valid an attribute by name"into another concept?Are there better names for the concept?
