Hi,
For some reason, at least the "VALUES" keyword in language SPARQL is not recognize by syntaxhighlight.
See for instance https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries/examples#Wikidata_items_of_Wikipedia_articles where VALUES is in black but should be highlighted in red.
PS: I've checked, this is standard SPARQL (see https://www.w3.org/TR/sparql11-query/#inline-data-syntax ).
