/**
* librdf_new_uri_relative_to_base:
* @base_uri: absolute base URI
* @uri_string: relative URI string
*
* Constructor - create a new #librdf_uri object from a URI string relative to a base URI.
*
* An empty uri_string or NULL is equivalent to
* librdf_new_uri_from_uri(base_uri)
*
* Return value: a new #librdf_uri object or NULL on failure
