|
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. |
