Seqs are only allowed in the contents of element vectors. It doesn't make syntactic sense to encase attributes in a seq.

So it's intentional :)

I think I distilled too much the example, losing my intention :), I was trying to use the seq expanding facility to return attributes + element content from a function, like:

 (defn myf [] (seq '({:bgcolor "red"} "p content")))
 (html [:p (myf)])
 ;=> I expected  "<p bgcolor=red>p content</p>" but got "<p>{:bgcolor \"red\"}p content</p>"

Obviously I can fix this by passing the tag name to myf and making myf return all the element vector, but would be nice if the seq expansion worked in the same way it do with elements. So consider this as a suggestion, not as a bug report :)

This seems an fairly rare use-case, and it feels semantically wrong to group the attributes and content together in a seq. It will also impact performance, as it prevents some compiler optimisations.

For those reasons I think I'll keep the current behaviour the way it is. I'm afraid you'll need to pass the tag name to your myf function.

I understand, thanks for the reply!
