The uri type represents a Uniform Resource Identifier
(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
This type is in the value set and its semantics equivalent to the Uri textual convention of the SMIv2.";
