(last updated 2007-07-31) MIME media type name : Application MIME subtype name : Vendor Tree - vnd.eszigno3+xml Required parameters : None. Optional parameters : None. Note: The character set is always defined is the XML declaration of the file and it can be either UTF-8 or ISO-8859-2. Thus having a charset parameter would be redundant. Encoding considerations : 8bit This media type may require encoding on transports not capable of handling 8 bit text. Security considerations : The file consists of XML labels and unformatted text contents. Executable content is not allowed. While it is an XML signature file (adequate to RFC 3275 and ETSI TS 101 903 v1.2.2.), integrity of the most elements (the signed elements) is provided. It is not necessary to protect the content for confidentiality -- it depends on the application area and the decision of the users. In default case, confidentiality is not provided. But if someone decides that he/she needs confidentiality-protection, the original file can be encrypted and placed into a data structure having the same (vnd.eszigno3+xml) format. Existing application (e.g. MICROSEC e-Szignó 3.1) supports this operation. Interoperability considerations : The format fulfils the requirements of RFC 3275 and ETSI TS 101 903 v1.2.2. Published specification : https://www.microsec.hu/ds/e-szigno30.xsd Applications which use this media : MICROSEC e-Szignó 3.1 and some other applications. Additional information : 1.
