  Why does nobody think in reprogramming xml2array (and array2xml too), it's 
such a horrible stack-copy algorithm, and you could help the entire T3, not only 
TV. Every extension using flexforms!

  Just simply looking at it, it can run x faster just using identical code and 
references "&".

  And if there is such an XML that makes xml2array a hot-spot, we should 
integrate that into the test-set, so we can objectively verify performance- 
improvements.
