"""Parses a string of specific attributes into a dictionary.

The function takes a string formatted as query parameters and converts it into a dictionary
where each key-value pair corresponds to the parsed attributes. If the input string is empty
or results in no parsed attributes, an empty dictionary is returned.

Args:
    specific_attributes (str): A string containing query parameters to be parsed. Must be a string.

Returns:
    dict: A dictionary containing the parsed key-value pairs. Returns an empty dictionary if no
          attributes are parsed.

Raises:
    AssertionError: If `specific_attributes` is not a string.
