Hi,
I have a simple application that has a Flat File Header, Body and Trailer.
The idea is that flat-file disassembler just pulls out the body parts.  The
header and trailer parts have Tags, the body part does not.
This works as expected when:
1. there is a header and multiple body parts - but NO Trailer.
2. The Header, Body and Trailer Parts have Tags.

However if the Body parts have no Tags then the parser intreprets the
trailer as a body part :-(

On the Schema I've added some extra attributes e.g. parsing=complexity and
Lookahead depth=0 [means infinite? not 0] but it makes no difference.

I presume the problem is that LookAhead depth does not apply over the
Disassember?

Can this problem be resolved by configuration?

thanks

No, this cannot be resolved using configuration.  The probing algorithm
basically checks the first level only, and is quite forgiving overall.
This prevents us from having to read a significant portion of the document
into memory to make the determination.

As a general rule, if the document has a trailer, they both document and
trailer should be easily determined at the top level.
