Lift boolean or over predicates.

Qualify an ordinary name with the XSD namespace.

Predicate for comparing against an XSD-qualified name. (Also accepts unqualified names, but this is probably a bit too lax. Doing it right would require checking to see whether the current schema module's default namespace is XSD or not.)

We need a Parser monad for reading from a sequence of generic XML Contents into specific datatypes that model the structure of XSD descriptions. This is a specialisation of the polyparse combinators, fixing the input token type.

Get the next content element, checking that it matches some criterion given by the predicate. (Skips over comments and whitespace, rejects text and refs. Also returns position of element.) The list of strings argument is for error reporting - it usually represents a list of expected tags.

Get the next content element, checking that it has the required tag belonging to the XSD namespace.

Get the next content element, whatever it is.

Grab and parse any and all children of the next element.

Run an XsdParser on the child contents of the given element (i.e. not in the current monadic content sequence), filtering the children before parsing, and checking that the contents are exhausted, before returning the calculated value within the current parser context.

Check for the presence (and value) of an attribute in the given element. Absence results in failure.

Grab any attributes that declare a locally-used prefix for a specific namespace.

Predicate for whether an attribute belongs to a given namespace.

Tidy up the parsing context.

Given a URI for a targetNamespace, and a list of Namespaces, tell me the prefix corresponding to the targetNamespace.

An auxiliary you might expect to find in Data.List

Turn a qualified attribute value (two strings) into a qualified name (QName), but excluding the case where the namespace prefix corresponds to the targetNamespace of the current schema document.
