According to the HTML spec [1], the value of the "usemap" is an URI and the
space is therefore escaped [2].If you use SAXON, you could then use the
saxon:disable-output-escaping extension when creating the "usemap" with
xsl:attribute [3]. Then the value of "usemap" would be "My Component" and
thus illegal, but it would work on a browser... I think...
