Often whitespace-only data is not significant for the application, and the cost of allocating and storing such nodes (both memory and speed-wise) can be significant. For example, after parsing XML string `<node> <a/> </node>`, `<node>` element will have three children when `parse_ws_pcdata` is set (child with type [link node_pcdata] and value `" "`, child with type [link node_element] and name `"a"`, and another child with type [link node_pcdata] and value `" "`), and only one child when `parse_ws_pcdata` is not set. This flag is *off* by default.
