Finding the documentation for parsing data found in BLE Advertising Respones

This is not a programming related question. It's a question about where to find the right documentation.

If this is not the right place to ask, please let me know and I'll move the question

I'm working on a C++-Deamon for parsing recieved BLE Advertising Packages (like hcidump from bleuz). For this I'm focusing on parsing only LE Advertising Report events (Bluetooth Core Specification 7.7.65.2, S. 2382 ff)

E. g: I need to extract the local name and the 16-bit UUID. This information can be found (if broadcasted) in the field "data".

I can extract the data part from the Advertising Event Packet (since it's described in the Core Specification how these packages are arranged) but I can't parse the data. I wasn't able to find a description of the codes used in this data frame.

I also went through the Core Specification Supplement, but I couldn’t find the corresponding codes. I only found some examples:

So far I gained my knowledge about this by just going throught these (incomplete) list of examples I found and from looking at the source code of hcidump.c.

Now the question is: Where can I find the official complete list to those bytes/codes?

Just an example of the package content I revieve: 

Respone: 04 3E 1C 02 01 04 01 55 19 19 E4 8D FE 10 0F 09 54 65 73 74 
  20 49 50 53 50 20 6E 6F 64 65 C5

It should be able to extract the following data

HCI Event: LE Meta Event (0x3e) plen 28
    LE Advertising Report
      SCAN_RSP - Scan Response (4)
      bdaddr FE:8D:E4:19:19:55 (Random)
      Complete local name: 'Test IPSP node'
      RSSI: -61

After going throught the whole Bluetooth SIG, I finally found the site where these codes are described:
