Description: Separation Scheme in terms of a restricted class abstraction, deduction form of rabex2 4284. (Contributed by AV, 16-Jul-2019.)
Hypotheses
Ref Expression
rabexd.1  |-  B  =  { x  e.  A  |  ps }
rabexd.2  |-  ( ph  ->  A  e.  V )
Assertion
Ref Expression
rabexd  |-  ( ph  ->  B  e.  _V )
Distinct variable group:    x, A
Allowed substitution hints:    ph( x)    ps( x)    B( x)    V( x)
