	<li><tt>&lt;query&gt;</tt> element may be used to select a value from the source or target variable or message part. The computed value of the query must be one of the following:

	</li>
</ul>


<p>For from-specs, the <tt>role</tt> attribute must be specified, while for the to-spec, the assignment is only possible to the partnerRole, hence there is no need to specify the role. Therefore, the to-spec can only refer to a <tt>&lt;partnerLink&gt;</tt> of which the declaration specifies the partnerRole attribute. The type of the value referenced by partnerLink-style from/to-specs is always a <tt>&lt;sref:service-ref&gt;</tt> element.</p>

<p>An attempt during process execution to read a partner link before its partnerRole EPR is initialized results in the <tt><a href="#assign-uninitializedPartnerRole" title="uninitializedPartnerRole on assign">bpel:uninitializedPartnerRole</a></tt> standard fault. Partner roles of partner links are read when they are referenced in an <tt>&lt;<a href="/confluence/display/ODExSITE/invoke" title="invoke">invoke</a>&gt;</tt> or the <tt>&lt;from&gt;</tt> part of a <tt>&lt;copy&gt;</tt> in an <tt>&lt;<a href="/confluence/display/ODExSITE/assign" title="assign">assign</a>&gt;</tt> activity.</p>

<ul>
	<li>a single XML node, for example an attribute or an element</li>
	<li>text (i.e. a text node, CDATA section, string-valuedXPath-expression, etc...)</li>

<h4><a name="assign-LiteralVariant"></a>Literal Variant</h4>

<p>The type of the literal value may be optionally indicated inline with the value by using XML Schema's instance type mechanism (<tt>xsi:type</tt>). The literal content must be either a single element or text. An empty <tt>&lt;literal/&gt;</tt> element is equivalent to an empty text node.</p>
