Hi Zohar,

there are no such guidelines. may be someone else can help from his past
experience who has done much work into this.

But here is what i will do.

Xml tags have corresponding octet value. So 1 XML tag may consume 10
chars/bytes(in plaintext) BUT it will be replaced with 1 octet/byte.
Similarly, if you have url in your xml content, then http:// or http://www
also have corresponding octet value. So, size is reduced drastically.

So, the rough guess could be

a. count your 1 tag as 1 octet.
b. values can be considered as 1 octet but from/to numbers consume half as 2
digits constitute 1 octet.
c. every string value is suffixed with 1 extra octet (NULL) and sometimes 1
octet as prefix also.
d. add some octets for HEADER.

Adding all 4 above will be MAX size your PDU should take.

NOTE - Standard values also have their octet counterparts. like GPRS has
value 49(right ??)

Hope i didn't add much to the confusion you already have :-)
