-<h3>Asserter</h3>
-
-<p>An <dfn id="dfn-asserter">asserter</dfn> is a creator of PROV-DM records. An asserter is denoted by an IRI. Such IRI has no specific interpretation in the context of PROV-DM.</p>

-<span class="nonterminal">asserter</span> ::= <span class="nonterminal">IRI</span><br/>
-<span class="nonterminal">IRI</span> ::= <em>an IRI compatible with production IRI in [[!IRI]], enclosed in a pair of < (U+3C) and > (U+3E) characters </em>
-</div>

-<div class='issue'>
-Currently, the non-terminal <span class="nonterminal">asserter</span> is defined as IRI. We may want the asserter to be an agent instead, and therefore use PROV-DM to express the provenance
-of PROV-DM. We seek inputs on how to resolve this issue. This is <a href="http://www.w3.org/2011/prov/track/issues/217">ISSUE-217</a></div>

-<h3>Namespace Declaration</h3>
-
-<p>A PROV-DM <dfn id="dfn-namespace">namespace</dfn> is identified by an IRI reference [[!IRI]]. In PROV-DM, attributes, identifiers, and literals of with datatype <span
-class="name">xsd:QName</span> can be placed in a namespace using the mechanisms described in this specification. </p>
-
-
-<p>A <dfn id="dfn-namespaceDeclaration">namespace declaration</dfn> consists of a binding between a prefix and a namespace. Every qualified name with this prefix in the scope of this
-declaration refers to this namespace.
-A <dfn id="dfn-defaultNamespaceDeclaration">default namespace declaration</dfn> consists of a namespace. Every unprefixed qualified name in the scope of this default namespace declaration
-refers to this namespace.</p>

-<h3>Location</h3>
-
-<p><dfn id="dfn-Location">Location</dfn> is an identifiable geographic place (ISO 19112). As such, there are numerous ways in which location can be expressed, such as by a coordinate,
-address, landmark, row, column, and so forth. This document does not specify how to concretely express locations, but instead provide a mechanism to introduce locations in assertions. </p>
-
-
-<p>
-Location is an OPTIONAL attribute of entity records and activity records. The value associated with a attribute <span class="name">location</span> MUST be a <span
-class="nonterminal">Literal</span>, expected to denote a location.
