I'll assume you intended to work with parameter entities; then as Richard
pointed out this can be legal ... if the three syntax errors are corrected
("<ENTITY % Part" twice, "%Part2;") AND if this is found in an external
parameter entity not an internal one (which disallows PEs inside entity
declarations -- a WF constraint).

Right -- this would violate _validity_ constraints (but a nonvalidating
parser should accept it just fine):
<!DOCTYPE Bubba [
<!ENTITY % Part1 "<!ELEMENT ">
<!ENTITY % Part2 " Bubba ANY>">
<!-- next is a validity error in both internal
and external subsets -->
%Part1;%Part2;
]>
<Bubba></Bubba>
Another way to make an error out of your declarations is to make the
PEs be external, not internal -- then they'd not match full grammatical
productions.
