-# BDOC (ASiC-E) container format
-* Has **.bdoc** or **.asice** extension
+# BDOC (ASiC-E - Associated Signature Container Extended) container format
+* Has **.bdoc**, **.asice** or **.sce** extension
 * BDOC is a new digital signature format developed in 2014 to replace the old, DDOC (DigiDoc) digital signature format. 
 * The benefits of the new format include the higher security level, the long-term integrity of the signed documents, as well as the better compliance with international standards.
 * BDOC container is based on **ASiC-E** standard.
 * Signatures are stored in **XAdES** format.
 * Supports two signature formats: **BDOC-TM** and **BDOC-TS**
 * **BDOC-TM** signature format has **time-mark** ensuring long-term provability of the authenticity of the signature.
- * This format has been used as a default digital signature format in Estonia since 2015.
- * It is based on **XAdES baseline LT** signature format.
- * Recommended extension is **.bdoc**

+    * Recommended extension is **.bdoc**
 * **BDOC-TS** signature format has **time-stamp**.
- * In contrast to the BDOC-TM format, long-term provability of the authenticity of the signature is ensured by time-stamps.
- * It is based on **XAdES baseline LT** signature format and uses RFC3161 based time-stamps which makes it highly compliant in international context.
- * To ensure better compliance with international standards, it's recommended to sign documents with the **BDOC-TS time-stamp** signature profile.

 * **.bdoc** or **.asice** file is in fact a ZIP container with the signed files, the signatures and the protocol control information and can basically be opened by any program that recognizes the ZIP format.
+* It is recommended not to use special characters in the data file’s name, i.e. it is suggested to use only the characters that are categorized as “unreserved” according to RFC3986 (http://tools.ietf.org/html/rfc3986).
+
+# ASiC-S (ASiC-E - Associated Signature Container Simple) container format
+* Has **.asics** or **.scs** extension
+* Container associates one data file with either:
+  - one signature file containing one or more detached digital signature(s) that apply to it; or
+  - one time assertion file containing a time assertion that apply to it.
+* This format is used for timestamping the old DDOC containers in order to prove the inviolability of documents.

 * Has **.ddoc** extension

 * The DigiDoc container includes the source files (the files that were signed) as well as the signatures that are related to the signed file(s)
 * Every signature contains the certificate, validity confirmation and the validity confirmation service certificate.
