XML-Schema-Catalog is a command line tool to parse and manipulate XML schema location files.

XML schema location files offer a way to locate the schema for a XML-document. They have been defined by XML-Guru James Clark (as apart of his nXML-Emacs mode).

As James wrote: "Unlike DTDs, RELAX NG does not specify a way to locate the schema for a document. nXML mode's way is to use a list of schema locating files. A schema locating file is an XML document specifying rules for locating a schema. It must be valid with respect to the schema locate.rnc. Each file specifies a list of rules. The rules from each file are appended in order. To locate a schema each rule is applied in turn until a rule matches. The matching rule is then used to determine the schema."

Now what's needed is a tool to manipulate these schema location files, something like 'xmlcatalog' is for DTD catalogs. This is what XSL-Schema-Catalog does.
