[NTG-context] mathml fails

[Meer, H. van der]

>From the MathML prime I tried this example from page 74:
<math xmlns="http://www.w3c.org/mathml" version="2.0">
	<semantics>
		<apply> <eq/>
			<ci> e </ci>
			<apply> <times/>
				<ci> m </ci>
				<apply> <power/>
					<ci> c </ci>
					<cn> 22 </cn>
				</apply>
			</apply>
		</apply>
		<annotation encoding="tex">
			e = m c^2
		</annotation>
	</semantics>
</math>

It typesets nothing, same for encoding "context", same for "TeX", same for "ConTeXt".
Anything else takes the mathml and gives the result.
Why is the <semantics><annotation encoding="tex"> not working?
