Create a collator from a parameterized URI

Specified by:

resolve in interface CollationURIResolver

Parameters:

uri - the collation URI as written in the query or stylesheet

base - The base URI of the static context where the collation URI appears. The base URI is available only in cases where the collation URI is resolved at compile time; in cases where the collation URI is not resolved until execution time (typically because it is supplied as an expression rather than as a string literal) this parameter is currently set to null.

config - The configuration. Provided in case the collation URI resolver needs it.

Returns:

null if the collation URI is not recognized. If the collation URI is recognized but contains errors, the method returns null after sending a warning to the ErrorListener.
