wouldn't it be possible to set a reference to the contents entry? so the
visualization of the signature value on the pdf would happen after signing the
document but this wouldn't affect the hash of the document (and therfore the
authenticity of the signature) because the document isn't changed. do you think
that could work and how would you implement that in pdf?

thanks in advance
best regards 
JE
