The question for DTDs has been answered (and deemed off-topic).
If you want to detect in a stylesheet that the <ssn> is non-numeric, try:
<xsl:if test="string(number(ssn))='NaN'">
or
<xsl:if test="translate(ssn, '0123456789', '')">
The former tolerates leading and trailing spaces and a decimal point, the
latter does not.
