Like this?

An extension expression consists of one or more pragmas, followed by an
optional expression (the extension expression's associated expression).

I guess I¹m not convinced that the expression always provides fallback
behavior. For instance, in this example, the expression is evaluated
whether or not the pragma is recognized:

declare namespace exq = "http://example.org/XQueryImplementation";
   (# exq:use-index #)
      { $bib/book/author[name='Berners-Lee'] }


We provide two examples, one is a fallback expression, the other one
isn¹t. I¹m not sure that fallback expressions are the main use.
