<p>In some serialization formats it is common to abbreviate <a title="IRI">IRIs</a>
- that start with <a title="namespace IRI">namespace IRIs</a> by using a
- <a>namespace prefix</a> in order to assist readability. For example, the IRI
- <code>http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral</code>
- would be abbreviated as <code>rdf:XMLLiteral</code>.
- Note however that these abbreviations are <em>not</em> valid IRIs,
- and must not be used in contexts where IRIs are expected.
- Namespace IRIs and namespace prefixes are <em>not</em> a formal part of the
- RDF data model. They are merely a syntactic convenience for
- abbreviating IRIs.</p>
