Is 'microparsing' something readily defined with a declarative unpacking
mechanism?

Or does it bind more tightly to a particular processing environment?

Unfortunatly it is bound to a processing environment. Mainly because there
are to many
syntaxes which are not readily handled by "readable" regular expression
or other usable
declarative technologies.
The mircoparsing binding is just a named mapping to/from a string based
type and an equivalent XML schema.

Regular expresssion may be a declarative approach that an handle a number
of useful use cases.
But what is the result after applying one or more reqexps, a xml fragment
or... ?
