    Convert a dictionary of attributes to a single string.
    The returned string will contain a leading space followed by key="value",
    XML-style pairs. In the case of a boolean value, the key will appear
    without a value. It is assumed that the keys do not need to be
    XML-escaped. If the passed dictionary is empty, then return an empty
    string.

    The result is passed through 'mark_safe' (by way of 'format_html_join').
