Oh, those are just the well known problems with names as identifiers :-)

Apparently there are names used by several ?South American? tribes, 
which have components which are only to be shared with family members 
etc. -- hence the need for a <given 
confidentiality="foo">Fribbet</given> attribute. Names and birthdates 
are not always good unique identifiers, particularly when you can easily 
have *multiple* John Smiths on the same patient floor etc. which is why 
hospitals use their own unique IDs -- social security numbers are not 
entirely without problems, in two situations:

1) SSNs are *reused*, ostensibly when people die, but nonetheless.
2) Illegal immigrants often "borrow" a SSN from a relative. Not great 
when they don't also share the same medical conditions, allergies, 
medications etc.

In cases where it is really important to know who we are dealing with, 
we attach a photo to the chart.

But I digress...

In any case to deal with aliases in specific is why I have the "type" 
attribute on the <person.name> element. e.g.

    <person.name type="alias">
    <id authority="U.S. Social Security Administration" 

In any case, that is perhaps more detail than needed for many 
applications, but for me its everyday stuff :-)
