Currently, a known limitation is:
RadPdfProcessing currently supports only signing of a single signature field. Signing more than one signature field will result in invalidation of all signatures except the last one.
Please support signing multiple signature fields. We are heading into 2022 and it's more essential than ever to be able to sign multiple signature fields.
OpenDocument Format is an open format for many software supported like OpenOffice, I hope the Telerik Document Processing libraries could support for import/export format.
Revisions in WordprocessingML provide a mechanism for storing information about the evolution of the
document (i.e. the set of modifications made to a document by one or more authors).
