I keep finding that how different systems handle document fragments is a
useful indicator of how they look at the world. React is a pretty
popular framework from Facebook, one I mostly like except for odd things
deriving from their particular mixture of markup and JavaScript.
They recently added more explicit fragment handling, and it might be
worth your time to explore it:
Among other things, their requirement of key attributes (but no other
attributes) in some contexts and their prohibition of attributes in
other places suggest a more element-centric approach than I've seen in a
while. Attributes remain available through other syntactical
approaches, but shortcut syntaxes tend to be a good indicator of how
developers want their tools used.
