The block had to be identified by a signature line. By default, the first
line is used as signature, or the line pointed to by signature_offset. If
signature_offset points outside the block, a signature line can be passed as
signature argument. Note: if 'signature' is None (the default), a negative
signature_offset is interpreted as index in a list (e.g. -1 means the last
line), otherwise the it is interpreted as the number of lines before the
first one of the block the signature must appear.
The parameter 'id' allow to distinguish between different calls to this
function in the same validation code.
