HolgerKnublauch has just submitted a new pull request for https://github.com/w3c/data-shapes: == #314: Made focusNode an explicit param of exprEval, SPARQL-based expressions now pre-bind all scope vars == <!-- # Pull request instructions (Note that text between the HTML comments will be recorded in this pull request's source for future editing, but will not render on Github.

This is cleaner because this variable really has a special status (e.g. it's called this in SPARQL) and it usually has a value (except in sh:targetNode). - The SPARQL-based node expressions now accept the scope vars as parameters. This makes it possible to define user-defined (SPARQL) functions through custom node expression types. For map-based NEe, these would be simple name-value pairs for the input parameters. For list-based NEs, these could be arg1, arg2, arg3 etc. The NE document can specify the details, but the SPARQL document does not need to change further to accommodate the use cases.
