The MathML Acid1 Test

1. $\Gamma \left(\text{toggle}\right)={\mathrm{CC0000}}_{16}$
2. $\tau (\text{the way},+260)=\underset{\text{old}}{\text{i grow}}$
3. $\text{the world ends}=\{\mathrm{bang},\mathrm{whimper}\}$
4. $\rho \left(\underset{\text{old}}{\text{i grow}}\right)=\frac{80}{120}=\frac{2}{3}$
5. $𝒜\left(\text{pluot?}\right)={120}^2=14400$
6. $\sigma \left(\stackrel{\text{sing to me,}}{\text{erbarme dich}}\right)=\sqrt{14400}=120$
7. $ℌ\left(\text{toggle}\right)=ℌ\left(\begin{array}{ccc}\text{the way}& \text{the world ends}& \underset{\text{old}}{\text{i grow}}\\ \text{pluot?}& \stackrel{\text{bar}}{\text{maids,}}& \stackrel{\text{sing to me,}}{\text{erbarme dich}}\end{array}\right)$

This may appear a nonsensical document, but is at least a syntactically valid HTML 5 document. All 100%-conformant HTML 5 agents should be able to render the MathML elements above this paragraph in a similar fashion as this reference rendering (MathJax).
