+Summary: Problem with feeding pre-encoded X509 extensions into Mono
+
+If you feed the DER encoding of a X509 extension into the ext(ASN1)
+constructor, an error occurs when Mono, later, puts the extension back
+together.The extension value is then wrapped two times in an octet-string
+instead of just one.
+
+Example:
+
+1) construct key usage extension outside of MONO
+  ext = ...
+
+2) feed it to mono
+  Mono.Security.ASN1 asn1 = new Mono.Security.ASN1(ext)
+  monoExt = new MONO.X509.Extensions.KeyUsageExtension(asn1);
+
+3) get DER encoding of Mono extension
+  byte der = monoExt.ASN1.GetBytes()
