HML Spec: Does 'sample' need additional status attributes?

[dvaliga]

In discussions about the definition of the 'sample' element in the HML beta spec, it was pointed out that there may be cases where data is sent as a no-make. In the past there have also been special instructions sent for no-interp and no-reports. Does it make sense to add an attribute or two to the 'sample' node for these conditions rather than overloading haploid type (for instance) by sending "0000"? Example: send " ..." instead? Or should these special cases just be handled using the optional 'property' element and kept out of the general HML specification.
