Detailed Description

Experimental and untested: represents a "path" to access a node.

Syntax:

• "." => root node
• ".[n]" => elements at index 'n' of root node (an array value)
• ".name" => member named 'name' of root node (an object value)
• ".name1.name2.name3"
• ".[0][1][2].name1[3]"
• ".%" => member name is provided as parameter
• ".[%]" => index is provied as parameter
