    The SVG specification defines three properties to reference markers: marker-start, marker-mid,
    marker-end. It also provides a shorthand property,marker.  Using the marker property from a style sheet
    is equivalent to using all three (start, mid, end). However, shorthand properties cannot be used as presentation attributes.
