 // Description:

 // 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.
