It is syntactically similar to SPARQL, which is why a lot of the productions of ShExCLexer are copied from SparqlLexer, but at the same time has enough differences that I feel it?s better to simply copy the productions rather than trying to share them between the two lexers (compare e.?g. PN_LOCAL_ESCAPE_CHARS or IRIREF). The example file purports to be a brief schema for Pygments lexers, which I put together from scratch to avoid licensing issues with existing example schemas; it should not be taken too seriously.
