target 

The attribute target allows to specify if the link should e.g. be openend in a new window (_blank) or in the
same window (_top). The attribute allows any strings. If you want to limit the allowed strings (e.g. only '_blank' and '_top') then you'll need to add a xs:redefine section to your validate.xsd file instead of the xs:include sections that includes elml.xsd and redefine the this attribute group as to only allow the specific strings for the attribute target.
