I am educating myself on the product. The environment is V6 CSD5 on WINXP
A simple flow
MQINPUT-COMPUTE-MQOUTPUT
I am using debug to observe the variables.

I tried to find the length of the properties folder by this ESQL

SET HEADERL = LENGTH(ASBITSTREAM(InputRoot.Properties));

But HEADRERL is always zero (observed by running debug)

So I try
SET HEADERL = LENGTH(ASBITSTREAM(InputRoot.MQMD));

This returns the length of the MQMD.

This is the same regardless if the input message is using the BLOB parser or XMLNS parser.

Did I miss something or this is normal?

This is expected behavior. The Properties are a "holding place" to allow for passing or setting values that will ultimately impact the MQMD. Jeff might give you a much better information when working with http nodes...

You might want to read up about the Properties node in the manual...

I'd be surprised if the Properties tree can serialize at all...

The thing to be aware of with Properties in v6 is that Properties will override any protocol specific header. So Properties.ReplyIdentifier, if set, will override the HTTP Reply Identifier or the MQMD.CorrelID...
