[Mediawiki-l] Order of tag extensions

[Javier Bezos]

Given the following text

<out2>blah <in2>blah</in2></out2>
<out1>blah <in1>blah</in1></out1>

where out1, in1, in2, out2 are tags defined as usual in
that order. In which order are these tags "expanded"?

out1 in1 in2 out2 (ie, as defined)?
out2 in2 out1 in1 (ie, as found)?
in2 out2 in1 out1?
Someting else?

Thanks
Javier
