static int	ComparePaths (const RElementPath_t &path1, const RElementPath_t &path2)
	Compare two paths, Returns number of elements matches in both paths.
static int	ExtractItemIndex (std::string &name)
	Extract index from name Index coded by client with ###<indx>$$$ suffix Such coding used by browser to identify element by index.
static EContentKind	GetContentKind (const std::string &kind)
	Find item with specified name Default implementation, should work for all.
static std::string	GetPathAsString (const RElementPath_t &path)
	Converts element path back to string.

	Returns sub element.
static RElementPath_t	ParsePath (const std::string &str)
	Parse string path to produce RElementPath_t One should avoid to use string pathes as much as possible.
