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