The value of the quantitative value or property value node.<br/><br/>
<ul>
<li>For <a class="localLink" href="/QuantitativeValue">QuantitativeValue</a> and <a class="localLink" href="/MonetaryAmount">MonetaryAmount</a>, the recommended type for values is 'Number'.</li>
<li>For <a class="localLink" href="/PropertyValue">PropertyValue</a>, it can be 'Text', 'Number', 'Boolean', or 'StructuredValue'.</li>
<li>Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.</li>
<li>Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.</li>
</ul>
