Age #4
Description
Instead of Age just a string. I would suggest we leverage what we had for the eCVI – and change it a bit. Instead of:
< xs:attribute name="Age" use="optional" type="xs:string" />
Can we have:
< xs:attribute name="Age" use="optional" type="AgeType" />
< xs:attribute name="DOB" use="optional" type="DOBType" />
Defined as:
< xs:simpleType name="AgeType">
< xs:annotation>
< xs:documentation>This can be an age specified as a number of days, weeks, months or years (suffixed with d, wk, mo or a to designate which)
The age definitions adhere to UCUM - http://unitsofmeasure.org/ucum.html/xs:documentation
