I think what you are looking for is:

xsl:value-ofselect="
count(/header/policy/requirement[ldor_requirement_ifa='Y' and
(ldor_requirement_code='A21C' or
ldor_requirement_code='A50A' or
ldor_requirement_code='OTHR')] )"/>

You can't use "and" and "or" to combine node-sets, only to combine
booleans.
