    Yes. <br>
    <br>
    The tag highway=residential says that is a road here,  a physical
    presence.<br>
    <br>
    The tag surface=grass says that whatever is here has a grass
    surface, but does not say what the physical presence is. <br>
    <br>
    If there is a thing tagged with both highway=residential and
    surface=grass then it says there is a road with a grass surface. <br>
    <br>
    For change tables they would commonly be combined with toilets,
    possibly other things too like libraries, community halls, camp
    sites etc.  <br>
    <br>
    So the description of surface does not say what the physical
    presence is, nor should change table. For change table it is the
    provision of the activity. <br>

                <div>the difference of a feature and a property is that
                  a property cannot be tagged alone, it requires a
                  feature (e.g. "surface", or "oneway", or "height"). On
                  the other hand, a feature is defining a "thing", e.g.
                  a highway defined through the tag "highway". It is not
                  a property, but a feature (and the values are
                  different "classes" of this feature).</div>
                <div><br>
                </div>
                <div>OSM does actually not explicitly make this
                  distinction (AFAIK), but it is implicit in how people
                  are using the tags.<br>
