My software writes the following string to an "HR" PPS object:

"is_valid::TRUE\nHR::0\n"

When I subsequently read from the object, I get the following string:

"@HR\nHR::0\nis_valid::TRUE\n"

Obviously, the order of the attributes in my read result is not what I expected. Is the first string above the correct 
way to write multiple attributes to a PPS object? 

Thanks,
Chris
