Syntax Symbols for query language syntaxes

Fields in com.hp.hpl.jena.query declared as Symbol

static Symbol	ARQ.constantBNodeLabels Controls bNode labels as <_:...> or not - that is a pseudo URIs.

static Symbol	ARQ.enablePropertyFunctions Enable built-in property functions - also called "magic properties".
static Symbol	ARQ.extensionValueTypes Expression evaluation without extension types (e.g.

static Symbol	ARQ.javaRegex Symbol to name java.util.regex regular expression engine
static Symbol	ARQ.optDistinctToReduced Context key controlling whether a DISTINCT-ORDER BY query is done by replacing the distinct with a reduced.
