    trac/219: append with mixed content creates unbound ElementContent

    This occured only with wildcards, and was due to too lax filtering of
    unrecognized values.  Only material that has enough information identify
    an element may be added as a wildcard.  Other material may be accepted
    as mixed content, if the type permits this.
