+      <text>The domain-name type represents a DNS domain name.  The
+name SHOULD be fully qualified whenever possible.
+
+Internet domain names are only loosely specified.  Section
+3.5 of RFC 1034 recommends a syntax (modified in Section
+2.1 of RFC 1123).  The pattern above is intended to allow
+for current practice in domain name use, and some possible
+future expansion.  It is designed to hold various types of
+domain names, including names used for A or AAAA records
+(host names) and other records, such as SRV records.  Note
+that Internet host names have a stricter syntax (described
+in RFC 952) than the DNS recommendations in RFCs 1034 and
+1123, and that systems that want to store host names in
+schema nodes using the domain-name type are recommended to
+adhere to this stricter standard to ensure interoperability.
+
+The encoding of DNS names in the DNS protocol is limited
+to 255 characters.  Since the encoding consists of labels
+prefixed by a length bytes and there is a trailing NULL
+byte, only 253 characters can appear in the textual dotted
+notation.
+
+The description clause of schema nodes using the domain-name
+type MUST describe when and how these names are resolved to
+IP addresses.  Note that the resolution of a domain-name value
+may require to query multiple DNS records (e.g., A for IPv4
+and AAAA for IPv6).  The order of the resolution process and
+which DNS record takes precedence can either be defined
+explicitly or may depend on the configuration of the
+resolver.
+
+Domain-name values use the US-ASCII encoding.  Their canonical
+format uses lowercase US-ASCII characters.  Internationalized
+domain names MUST be A-labels as per RFC 5890.</text>

+(URI) as defined by STD 66.
+
+Objects using the uri type MUST be in US-ASCII encoding,
+and MUST be normalized as described by RFC 3986 Sections
+6.2.1, 6.2.2.1, and 6.2.2.2.  All unnecessary
+percent-encoding is removed, and all case-insensitive
+characters are set to lowercase except for hexadecimal
+digits, which are normalized to uppercase as described in
+Section 6.2.2.1.
+
+The purpose of this normalization is to help provide
+unique URIs.  Note that this normalization is not
+sufficient to provide uniqueness.  Two URIs that are
+textually distinct after this normalization may still be
+equivalent.
+
+Objects using the uri type may restrict the schemes that
+they permit.  For example, 'data:' and 'urn:' schemes
+might not be appropriate.
+
+A zero-length URI is not a valid URI.  This can be used to
+express 'URI absent' where required.

+In the value set and its semantics, this type is equivalent
+to the Uri SMIv2 textual convention defined in RFC 5017.</text>

+
+A node-instance-identifier value is an

+All the same rules as an instance-identifier apply
+except predicates for keys are optional.  If a key
+predicate is missing, then the node-instance-identifier
+represents all possible server instances for that key.
+
+This XPath expression is evaluated in the following context:
+
+ o  The set of namespace declarations are those in scope on
+    the leaf element where this type is used.
+
+ o  The set of variable bindings contains one variable,
+    'USER', which contains the name of the user of the current
+     session.
+
+ o  The function library is the core function library, but
+    note that due to the syntax restrictions of an
+    instance-identifier, no functions are allowed.
+
+ o  The context node is the root node in the data tree.</text>
