This annotation a value that is of a particular syntax, such as Java syntax
or regular expression syntax. This can be used to provide syntax checking of
constant values at compile time, run time checking at runtime, and can assist
IDEs in deciding how to interpret String constants (e.g., should a
refactoring that renames method x() to y() update the String constant "x()").

Value indicating the particular syntax denoted by this annotation.
Different tools will recognize different syntaxes, but some proposed
canonical values are:

 "Java"
 "RegEx"
 "JavaScript"
 "Ruby"
 "Groovy"
 "SQL"
 "FormatString"

Syntax names can be followed by a colon and a list of key value pairs,
separated by commas. For example, "SQL:dialect=Oracle,version=2.3". Tools
should ignore any keys they don't recognize.
