+// This file contains definitions for interpreting the trie value of the idna
+// trie generated by "go run gen*.go". It is shared by both the generator
+// program and the resultant package. Sharing is achieved by the generator
+// copying gen_trieval.go to trieval.go and changing what's above this comment.
+
+// info holds information from the IDNA mapping table for a single rune. It is
+// the value returned by a trie lookup. In most cases, all information fits in
+// a 16-bit value. For mappings, this value may contain an index into a slice
+// with the mapped string. Such mappings can consist of the actual mapped value
+// or an XOR pattern to be applied to the bytes of the UTF8 encoding of the
+// input rune. This technique is used by the cases packages and reduces the
+// table size significantly.
+//
+// The per-rune values have the following format:
+//
+// if mapped {
+// if inlinedXOR {
+// 15..13 inline XOR marker
+// 12..11 unused
+// 10..3 inline XOR mask
+// } else {
+// 15..3 index into xor or mapping table
+// }
+// } else {
+// 15..14 unused
+// 13 mayNeedNorm
+// 12..11 attributes
+// 10..8 joining type
+// 7..3 category type
+// }
+// 2 use xor pattern
+// 1..0 mapped category
+//
+// See the definitions below for a more detailed description of the various
