The log accessor is used to serialize the operand resource to the system
log. It is useful for debuging, for critical failure reports or for status messages. System loggers
are configured by the administrator. Log entries created using this accessor are created at the
APPLICATION level.
Operator Syntax
The log accessor takes an optional operator.
If the /log/string element exists then the text of the root element of the operand is serialized.
If it doesn't exist or there is no operator then the whole operand is serialized to the log.
An optional info, warning, or severe element
sets the logging severity. By default the logging level is application.
