There are several geometric constraints on a sketch that are not visible to
the end user. For instance, if there is just a line in the sketch, there are
2 coincident constraints (one between the line and start sketch point and
the other between the line and the end point). These are not visible to the
end user (so the 'Show All Constraints' won't show these), but the API
collection picks up these constraints as well. And such "internal"
constraints cannot and should not be deleted. Perhaps the API can do better
in identifying such constraints using a special property and/or failing on
the Delete method. But unfortunately, there currently isn't a way to
identify them.
