+// Attribute Look-Up-Table header
+// The Attribute Lookup Table maintains a global set of unique IDs to be defined for document
+// node attributes and language tags. It does this by generating a unique ID for any descriptor
+// passed to it. This descriptor is in fact a pointer to a copy of the string. Once a string
+// has been seen once, any further references to it will map back to the same ID (pointer)
+// value.
