Errors in PSD specification

$

Hello,

 

I am trying to make a program, which loads and parses PSD files. I am using this specification: http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/ from June 2013.

 

I have found many errors and incomplete things. The last problem I am stuck at is Virtual Memory Array List - http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/#VirtualMe moryArrayLis

 

In docs, it says, that there is

 

4   Boolean indicating whether array is written

4   Length

4   Pixel depth: 1, 8 or 16

1   Compression mode of data to follow. 'Pat2' compression is zip.

Variable    Actual data based on parameters and compression

 

But all PSD files I have actually contain

 

4   Boolean indicating whether array is written

4   Length

4   Pixel depth: 1, 8 or 16

16  Rectangle for pattern (same rectangle is there twice + once for each pattern channel = five times!)

2   Pixel depth again, but as Short

1   Compression mode of data to follow. 'Pat2' compression is zip.

Variable    Actual data based on parameters and compression

Varialbe    Some random bytes of random length (20 ~ 200 bytes). No idea what is inside, what they are used for. About half of them are "continuous" zeros.

 

Can Adobe specify these data and update the document? I think those errors are there for years.
