Hello again, I answered your previous message and maybe it will help, there
is indeed an ambiguity for xml schema between your elements because they are
all declared globaly and xml schema does not know wether or not they can
appear more than once, or so I believe.

Whichever the reason, an easy fix would be to use, in this particular case,
local element declarations, for all said elements in your <xsd:choice> or at
least for either :
the two Symkey and SymkeyErreor element or
the element containing SymkeyWithSymkeyErrorGroup group

Hope it helps.
