:mrdocs:

Create an object of (template parameter) `ELEMENT_TYPE` at the specified `address`, constructed by forwarding the specified `argument1` and the (variable number of) additional specified `arguments` to the corresponding constructor of `ELEMENT_TYPE`. If `ELEMENT_TYPE` supports `bslma`‐style allocation, this allocator passes itself to the constructor. If the constructor throws, the memory at `address` is left in an unspecified state. Note that, in C++03, perfect forwarding is limited such that any lvalue reference in the `arguments` parameter pack is const‐qualified when forwarded to the `ELEMENT_TYPE` constructor; only `argument1` can be forwarded as an unqualified lvalue. The behavior is undefined unless `address` refers to a block of sufficient size and properly aligned for objects of `ELEMENT_TYPE`.
