It's not used as much as a directly authored form - it's the programmatic building of a query that is best done in the algebra.  It's fine when you do use it like that, not that the ARQ-supported form is XML.  Do have to like writing a purely functional query form in prefix notation.

Personally, I find it just fine.

But XML syntax for the tool chain can be done as SPARQL query string -> parser -> XML form.  Writing the XML form of the AST is going to verbose in any design and a machine can easily do it for you.

Need to cover SPARQL/Update if the WG decides to work on that feature.



and tick the algebra box.  I know you are not afraid of lots of (()).
