That is right. From the perspective of the encoder they are hash tables
from the perspective of the decoder they are array tables.
There are a bunch of tables for different types of information (local
name, attribute II, element II, namespace URI, namespace prefix. This
can reduce the search space and the size of table indexes that are encoded.
After a fast infoset document is parsed there will be (conceptually) a
final vocabulary that represents all the table entries created while
parsing (same applies after encoding an XML infoset to a fast infoset
document).
