This looks good. One small caveat:

alias DocumentType = SomeDocument!(ObjectVersion._1_0, 
ObjectEncoding.UTF8);
alias DocumentType2 = SomeDocument!(ObjectEncoding.UTF8, 
ObjectVersion._1_0);

These are not the same type; they're two identical types with 
different mangles. You can fix that with a layer of indirection:

template SomeDocument(Options...)
{
   alias SomeDocument = 
SomeDocumentImpl!(OptionsOf!(DocumentParams, Options));
}
