password datatype in RDF

We have an RDF based form, where some of the details of the presentation 
are decided late, based on the data and its schema.

For our application, we need to enter various SMTP setup information in 
this form, including a username and password.
Right now, the password appears in clear-text ... :(

A colleague suggested that we invent a new datatype:

tq:password rdfs:subClassOf xsd:string .

and then upgrade our form presentation software to treat this datatype 
with the conventional ****s

That seems like a reasonable approach, has it been done before? Is there 
a datatype to reuse, or some other method?

thanks

Jeremy
