Comment 1 for bug 746710

From the link above: "Some keys can have multiple values. In such a case, the value of the key is specified as a plural: for example, string(s). The multiple values should be separated by a semicolon, and the value of the key should have a semicolon as trailing character. Semicolons in these values need to be escaped using \;. "

Added those and updated the descriptions and fixed the names (matching those displayed by the tools itself).
