109 Document ::= Binary_Document | XML_Document
111 Document is Base64 encoded binary format or XML.
113 There exist special Document type, ESS format, that can exist in Content only
116 Note: ESS format is special XML language designed as interface between
117 Electronic Document Systems (ESS). It's defined in Appendix 4 of Provozní řád
120 Message with `malicious code' will be refused by ISDS.
122 Maximal total size of Documents in a Message is 10 MB. Binary document size is
123 size before encoding into Base64, XML document size is size in bytes as is
124 serialized inside SOAP request.
126 A Message can be addressed to 50 recipients at maximum.
128 Life time of Message:
130 – 90 days for delivered message
131 – unlimited for delivered through fiction messages, however they can be
132 moved to off-line storage after 90 days. User can request to move the
133 Message back into his box (off-line only currently).
135 Deleted messages are stored off-line as Envelope only without Content.
137 Note: Delivery through fiction is currently defined as new unread for more
138 than 10 days after delivery.
144 Emeded digital signatures are PKCS#7 to avoid expensive XML canonicalization.
150 There exists special message type iniciated by ISDS (i.e. from system, not from
151 other box). Such message has reserved from-box `aaaaaaa' (7 × `a') value and
152 sender type `0' and it contains always document of type HTML. There are
153 following cases defined:
155 1 Outgoing message contained malicious code
156 2 You, administrator, deleted other user
157 3 Outgoing message could not been delivered because recipeient box had been
159 4 Outgoing commercial message has not been accepted by recipient
160 5 User has been added to the box
161 6 User permissions has been changed
167 Users can allow commercial message receiving explicitelly. Commercial message
168 are not considered as accepted by recipient automatically (in opposite to
169 standard messages), recipient must call ConfirmDelivery to move message from
170 state Delivered (4) to state Received (6).
172 User can request to assign permission to send commercial messages. Permission
173 can be assigned by Czech Post. Commecial recipient can not be searched. Sender
174 must know exact box ID.
176 Commercial message can be recognised by @dmType="K" in message envelope. If
177 @dmType is "V" or attribute is missing, message is so called public (i.e.
178 standard noncommercial with acceptence time outs etc.).
185 1 Message has been put into ISDS
186 2 Message stamped by TSA
187 3 Message included virues, infected document has been removed
188 4 Message delivered (dmDeliveryTime stored)
189 5 Message delivered through fiction (dmAcceptanceTime stored)
190 6 Message delivered by user login or user explicit request (in case of
191 commercial message) (dmAcceptanceTime stored)
192 7 Message has been read by user
193 8 Message could not been delivered (e.g. recipent box has been made
194 unaccessible meantime)
195 9 Message content deleted (thus can not be obtained on-line)
