                Given a string and a variable number of tag descriptors return XML fragment made
                by nesting the tags with the same hierarchical order they are listed on the command
                line. The tag descriptors can be a one element list (the tag) or an odd-length list whose
                first argument is the tag namme and the remaining elements are interpreted as 
                attribute name-attribute value pairs.
