<!--Maximum distance, in meters, from a target tree that neighbors can shade-->

<!--Sky mask angle - the minimum angle from the horizon, in degrees, that the
 sun can be seen-->
<!ELEMENT li_skyMaskAngle (#PCDATA)>
<!--As a simplification, the crown of shading neighbors can be assumed to extend
 down to the ground.  If not, the crown depth is calculated
 from allometric data.  Allowed values are 0 (crown extends to ground) and 1 
 (crown is calculated as having its usual depth).-->
