I think, in doubt, especially in SVGT1.2 author have to move structured information anyway into the metadata element and using the new RDFa attributes to indicate the role or property represented by the structured metadata. Because the structure of titles is typically simple (and authors should prefer the metadata with a role like tooltip anyway to provide a tooltip information instead of (ab)using the title element for a tooltip and to reduce the risk to corrupt the title with inproper content), the new possibilities with systemLanguage look pretty useful - of course, older viewers (what are currently mainly all viewers) do not care about this new feature. Therefore this is currently only a theoretical possibility - hopefully it can be used in the near future. There are more problems however with the desc element in SVGT1.2, because it cannot contain a structure anymore. Therefore authors have to move such structured descriptions in the metadata element, providing a proper CURIE for role or property: <metadata role="http://www.w3.org/TR/SVGTiny12/struct.html#DescElement" property="http://www.w3.org/TR/SVGTiny12/struct.html#DescElement"> <!-- structured description --> </metadata> This looks funny within SVG, but there is no better way to do it in SVGT1.2 ;o) Because it is much more complex for viewers to identify this as a structured description, the probability is significantly lower, that this is available for a wide audience. With all this the complexity of content increases, even more if such constructions have to be used in SVG in 'HTML5', having not even included such important RDFa features ...
