+# cannot use the '|' pipe character in your string. If the '|' delimiter is not

+# Context details are of the format textgroup:type:objectid:property.

+# The textgroup determines the category of the string and the type is where
+# the string originates. You can further denote a specific object ID (e.g. node
+# ID), if appropriate, and then the final property item can be used if more
+# specificity is still required. Generally, a simple textgroup:type context is
