Javascript has an ECMA standardized extension that supports this
(ECMA-357 or E4X).
Groovy has a different approach that doesn't blend the two syntaxes,
but rather gives you more native syntax for constructing DOM trees (or
event streams; it wasn't clear from the description I saw today). That
makes perhaps more sense; it avoids the lexical ambiguities and a
parentheses-based syntax is easier to type than XML. Maybe this
example (which I am making up) suffices:
frag1 = element["some content"]
frag2 = element["some content",
child(attribute='value')["spam & egg"]]
