Normally, when you use a Channel, you should provide
which connect it to an external data store by reading and writing the resulting text.
By default, however, a Channel will read from standard input and write to standard
output. Alternatively, a Channel can be told to read or write from specific text files
using the SinkFile and SourceFile attributes, in which case no sink or source
function need be supplied.
Comment: Include textual comments in output?
Full: Set level of output detail
Indent: Indentation increment between objects
ReportLevel: Selects the level of error reporting
SinkFile: The path to a file to which the Channel should write
Skip: Skip irrelevant data?
SourceFile: The path to a file from which the Channel should read
Strict: Generate errors instead of warnings?
