+
+	collectionObject-full-ns.rng
+	
+	A schema defining the structure of an CollectionObject entity.
+		
+	This schema includes all of its components, rather than referring
+	to them via 'externalRef' references. As such, it can be used as the
+	basis for generating a W3C XML Schema (XSD) schema, via
+	James Clark's Trang utility (http://http://www.thaiopensource.com/relaxng/trang.html).
+	(Trang version 20081028 can't resolve such references.) 
+	
+	As a convenience, a 'rng-to-xsd.sh' script file, which trivially wraps Trang
+	to generate XSD from a RELAX NG schema, is provided elsewhere in this distribution.
+	
+	This schema also includes one rudimentary root namespace, scoped for the Release 0.1
+	"Hello World" demo.  We'll need to determine whether, and if so how, we can
+	accommodate multiple namespaces to compose entity objects from various schemas,
+	such as service metadata, and declarations for the default entity, a domain- or community-
+	provided entity, and site- or instance-specific version of an entity.
+
+	This schema was created for the CollectionSpace system,
+	http://www.collectionspace.org/
+	
+	It is written in the XML syntax of the RELAX NG schema language,
+	http://relaxng.org/

+	
+	A schema defining the structure of an CollectionObject collection
+	(list of multiple CollectionObjects).
+	
+	This schema includes all of its components, rather than referring
+	to them via 'externalRef' references. As such, it can be used as the
+	basis for generating a W3C XML Schema (XSD) schema, via
+	James Clark's Trang utility (http://http://www.thaiopensource.com/relaxng/trang.html).
+	(Trang version 20081028 can't resolve such references.) 
+	
+	As a convenience, a 'rng-to-xsd.sh' script file, which trivially wraps Trang
+	to generate XSD from a RELAX NG schema, is provided elsewhere in this distribution.
+
+	This schema was created for the CollectionSpace system,
+	http://www.collectionspace.org/
+	
+	It is written in the XML syntax of the RELAX NG schema language,
+	http://relaxng.org/
