Specify allowable age/DOB values

[pnrobinson]

Note that sometimes journals etc prefer to indicate an approximate age range rather than an exact age in years or even a DOB in order to reduce identifiability. Thus, using the general HPO age classes could actually be an advantage here.

[pnrobinson]

But of course the phenopacket syntax should also allow exact dates. There must be some ISO about this?

[mellybelly]

NISO date standard should be used for DOB. I can't seem to find anything in NISO for time quantification in years, months, days, etc. but is likely there somewhere?

For HPO stage ranges, we can use the HPO terms but for the purposes of pan-species representation, we still likely need to make a few adjustments to HPO in this regard.

We should review where we are and make sure we have good alignment for all organisms.
