SyntaxValidator.validate throws exception on invalid XML instead of returning error

[sherlock1982]

Since the function returns true or error I would expect it to not throw exceptions. Also like this it's not a drop-in replacement of original validator looks like

function validateXml(value: string): boolean {
    try {
        value = 'Not really an xml';
        return SyntaxValidator.validate(value) === true;
    }
    catch {
        return false;
    }
}
