Application ID: 12645909

Base Claim:
1. An apparatus comprising a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform the following: intercepting a communication from a sender to a receiver, the communication being formatted in a structured mark-up language, the mark-up language including at least one protocol primitive for an application that sends and receives communications, each protocol primitive including one or more protocol information elements that carry information about a communication, each protocol information element including lawful interception (LI) attributes that include at least one of a type of content and a level of interception; comparing a protocol primitive in the intercepted communication with a document type definition (DTD) for the mark-up language, to identify the LI attributes of the protocol information elements in the intercepted communication, the DTD specifying the LI attributes of the protocol information elements; and preparing one or more of the protocol information elements in the intercepted communication for transmission to an interception monitoring facility according to the LI attributes of the protocol information elements.

Claim 3:
3. The apparatus of claim 1 , wherein the executable instructions cause the apparatus to further perform the following: receiving a preliminary DTD including the protocol information elements of the mark-up language, without their LI attributes; and augmenting the preliminary DTD to include the LI attributes of the protocol information elements, wherein the LI attributes include (i) a type of content selected from a group of types including content of communication, interception-related information, and a combination of content of communication and interception-related information, and (ii) a level of interception selected from a group of levels representing different amounts of information to be transmitted to the interception monitoring facility.
