Remarks

This API writes the start element, the attributes, child elements / text, and the end element that corresponds to the specified value.

If the API fails, the state of input writer becomes undefined. The only APIs that may be used on the writer if this occurs are WsSetOutput and WsSetOutputToBuffer to return the writer to a usable state, or WsFreeWriter to free the writer.
