+# To simplify OPDS Catalog validation, we do not use Schematron to assert that

+
+# Note that this OPDS Catalog schema includes atom.rnc, so that schema must be
+# present for validation.
+# 
+# Note also that atom.rnc defines atomUri as text and not as xsd:anyURI, and so
+# wherever the Atom spec requires an IRI, the schema will not check the value
+# against any URI pattern or logic. The OPDS Catalog schema overrides atom.rnc

+# To simplify OPDS Catalog validation, we do not use Schematron to assert that

+# Instead we rely on Relax NG to describe one of three situations:
+# - the rel value is ".../acquisition/buy" and at least one opds:price element
+#   is required
+# - the rel value is ".../acquisition/borrow" or ".../acquisition/subscribe" or
+#   ".../acquisition/sample", in case opds:price elements may be
+#   included; or
+# - the value of the rel attribute is any other URI or an Atom-defined no-colon
+#   name, and no opds:price element is permitted
+
+# Note that this OPDS Catalog schema includes atom.rnc, so that schema must be
+# present for validation.
+# 
+# Note also that atom.rnc defines atomUri as text and not as xsd:anyURI, and so
+# wherever the Atom spec requires an IRI, the schema will not check the value
+# against any URI pattern or logic. The OPDS Catalog schema overrides atom.rnc
+# to provide a relatively accurate test. With the approval of XSD 1.1, the
