Possible typo in NOTES

In section XVII Strong Encryption paragraph 6, there is a possible typo:

Elastic buffers are also used inside compression blocks. The underlying
cypher may not be able...

Should "compression" be "encryption"? In the context, I'm assuming so.
If not, I can't find the code where elastic buffers are used in the
compressor.


Also, I'm assuming that while this is the model when using strong
encryption:

+----------+---------------------------------------------------------+
| version  | Encrypted data                                          |
| header   |                                                         |
+----------+---------------------------------------------------------+

|          +-----+---------------------------------------+------+----+
|          | EEE | Compressed data                       | TTTT | EE |
|          |     |                                       |      |    |
|          +-----+---------------------------------------+------+----+
|
|                +------+--+...................+---------+
|                | file |EA|                   | Catalog |
|                | data |  |                   |         |
|                +------+--+...................+---------+
^           
zero offset

Is the following model used when scrambling is used instead of strong encryption?


+----------+---------------------------------------------------------+
| version  | Encrypted data                                          |
| header   |                                                         |
+----------+---------------------------------------------------------+

|          +--------------------------------------------------+------+
|          | Compressed data                                  | TTTT |
|          |                                                  |      |
|          +--------------------------------------------------+------+
|
|                +------+--+...................+---------+
|                | file |EA|                   | Catalog |
|                | data |  |                   |         |
|                +------+--+...................+---------+
^           
zero offset


Thanks as always,
