The host string isn't quoted when creating XML in some similar code in
cmdPoolCreateAs ... but that's not necessarily a good justification.

Is there an existing routine to quote a string to make it suitable for
an XML attribute value?  (Something in libxml2, perhaps??)  I'm not even
sure of the correct syntax to quote a "'" in an attribute value, for
example.
