You can use the primitives to implement whatever OTHER standard (or non-standard) signatures you want. You can create Certificates, CMS messages, OCSP requests and responses, etc - all of which are signed structures.
I realize I MIGHT be feeding a troll here, but to say that OpenSSL is only useful for doing SSL/TLS, is completely inaccurate. However, what it is a toolkit. How you use those tools will depend both on how well you understand both the tool and the task at hand, but the toolkit is more than adequate for creating some form of signed Word Document.
