Of what does a notification package consist? ( Packet Structure )

Question

I mean what kind of header information and stuff besides the data. I could only find this for advertising packets. 
 A graphic or list like this would be nice: 
 byte 0-1 // byte 2-30 // byte 31 
 sendername // data // crc 
 and a citable source :)

Well citable source is easy: BT SIG specification 4.0 or higher;) If you mean "Handle Value Notification ATT method" it is standard PDU, isn't it? I'll leave these few drawings here but I believe you'd like to to get access to this presentation: original presentation by BT SIG from 2010 during official introduction of LE as part of BT 4.0 (member login required but registration is for free). 
 Cheers Jan 
 PDU on LE LL layer 
 
 PDU on LE ATT layer (no authentication) 
 
 PDU on LE ATT layer (authentication signature) 
 
 Note: 
 "Opcode" for "Handle Value Notification" ATT method is 0x1B.
"Attribute Parameters" consists of 16-bit ATT handle number and actual data.
