”The @gi attribute of <tagUsage> names the elements for which the rendition described in <rendition> is documented. The formal namespace in which the tags described in <tagUsage> are defined, must be specified in the @name attribute of a surrounding <namespace> element. The value of the @render attribute of <tagUsage> refers to <rendition> by way of the latter’s @xml:id attribute. This way, all <hi> elements inside <text> have ‘italic’ as their default style. The deviation to that rule is articulated in the third occurrence of <hi> by making use of the @rend attribute.”
