Create two XML files holding information for a simple, basic chat application

Create two XML files holding information for a simple, basic chat application. One XML file should hold data for a conversation/room. You should have elements/attributes as required to hold messages, usernames, submission time, chat room id, and any other information you think should be there. The chat conversation should have at least five messages. Think about what information you need to be able to store messages in a meaningful way. For example, can your data easily support sorting by submission time? If not, then perhaps the submission time format is insufficient. Can you identify who submitted the message? If not, then you need to tie the user to the message in some way. The second XML file should hold information for multiple chat rooms (i.e. a listing of chat rooms). You should have elements/attributes as required to hold chat room ids, chat room names, and any other information you think should be there. If you are having trouble getting started, try thinking about the type of information you'd see in a chat room conversation. Using your XML files as a base, create a Schema for each XML file.
