Consider "Schema Component Constraint: All Group Limited" from
http://www.w3.org/TR/xmlschema-1/#coss-modelGroup, which states:

  When a model group has {compositor} all all of the following must be true:
  1 one of the following must be true:
  1.1 It appears as the model group of a model group definition.
  1.2 It appears in a particle with {min occurs}={max occurs}=1, and
  that particle must be part of a pair which constitutes the {content
  type} of a complex type definition.
  2 The {max occurs} of all the particles in the {particles} of the
  group must be 0 or 1.


Since the resulting content model of the extension is a sequence of base 
content type (e.g. sequence), and derived content model (e.g. all), which does 
not meet 1.1 (because they're not in model group definition) and they aren't the 
content type of a complex type definition, because they're part of a sequence.

Also, according to the schema spec 
(http://www.w3.org/TR/xmlschema-1/#cos-particle-extend) you cannot extend an 
'all' content model unless you are only adding attributes.
