+// It was possible for a non-ASCII-lowercase string to be used when inserting
+// into the attribute collection if a hashtable encountered it during probing
+// while looking for the ASCII-lowercase equivalent.
+//
+// This caused such a string to be illegally used as an attribute name, thus
+// causing inconsistent behavior in future attribute lookup.
