Connection Context (I)

While the APM package, represented by the XOTcl object of type ::xo::Package, is
the central message redirector and dispatcher, instructions in your web application
execute in a context that they need to be aware of. Relevant context information is:

HTTP-level request information: request parameters, HTTP method-related information, headers, ...
Package instance parameters
Possibly, transaction-enabling information (e.g. session-related info bits)
Request monitoring
User- and community-related information

The XOTcl Core comes with a generic context facility that integrates various sources
of context information in a single entity: ::xo::ConnectionContext
