The following conventions are used in the specification of value syntax expressions:

-

a literal term (specified within quotation marks), when present, must appear exactly as specified - (excluding the quotation marks themselves);

a literal term (specified within double or single quotation marks), when present, must appear exactly as specified + (excluding the quotation marks themselves and after performing escape processing);

For example, the literal '\\' is interpreted as a single backslash, i.e., REVERSE SOLIDUS (U+005C).

concatenated (juxtaposed) terms mean that all terms must appear in the stated order, e.g., a b means that the terms a and b are present and the former precedes the latter;

a vertical bar (|) separates two or more alternatives, of which exactly one must appear;
