williamr@2: // The Attribute Lookup Table maintains a global set of unique IDs to be defined for document
williamr@2: // node attributes and language tags. It does this by generating a unique ID for any descriptor
williamr@2: // passed to it. This descriptor is in fact a pointer to a copy of the string. Once a string
williamr@2: // has been seen once, any further references to it will map back to the same ID (pointer)
