Above, we've stored all the in edges in an arrays named "permittedInEdges", "specifiedInEdges", "permittedOutEdges", and "specifiedOutEdges".
 +
 
 +
Each entry in each array is in this format:
 +
 
 +
[name of edge]<PROP>[name of predecessor]$SEP$[multiplicity]$SEP$[edge description]
 +
 
 +
...except that, if there are multiple entries from the same edge, they will be separated by "<MANY>",
 +
and the name of the edge will not be repeated, i.e., if there are two possible predecessors for a specific
 +
edge type, the format will be:
 +
 
 +
[name of edge]<PROP>[name of predecessor]$SEP$[multiplicity]$SEP$[edge description]<MANY>[name of other predecessor]$SEP$[multiplicity]

 +
...now we want similar information about inherited in edges:
 +
 
 +
--></noinclude>{{#arraydefine:parentsArray|{{{parents|}}}|,|}}<noinclude><!--
 +
 +
We gather the information on inherited edges as well, then defer to a helper template to print the actual tables
 +
 
 +
There's one tricky bit here: we need to have a <PARENT_SEP> separator if and only if a parent actually contributes connections. We do that by not using the separator argument of the #arrayprint:parentsArray, and instead printing <PARENT_SEP> after each one...which results in one small problem: there's an extra <PARENT_SEP> on the end that we need to remove...so we parse the result into an array again, slice off the final element with #arrayslice, and re-print it using <PARENT_SEP> as the separator.

For use on node kind pages, automatically lists edges declared on the current page.

If the parameter "parents" is given a comma-separated list of the parents of the node, inherited edges will also be listed.
