[ http://jira.qos.ch/browse/LBCLASSIC-22?page=com.atlassian.jira.plugin.system... ] Ceki Gulcu commented on LBCLASSIC-22: -------------------------------------

1) "generates humanly readable output" - the output is in a form that is readable to the human eye when browsing the text file containing the output from the XMLLayout. This _INCLUDES_ the time attribute which contains a humanly readable version of the timestamp, put in a location where it is useful in the situation where the human needs to read the logfile. I took great care in putting the linefeeds in the right places while maintaining DTD conformancy.

The output generated by XMLLayout_Blue (blue for the version currently shipping in logback 0.9.16) also generates "humanly readable" output. The timestamp attribute is *not* part of log4j.dtd, at least not on any currently shipping version of log4j. I am not sure one can just add unexpected attributes to a given element and still be DTD compliant. How about adding a comment which includes the date? A comment will satisfy the human reader without affecting DTD compliance.

2) Uses numeric XML entities instead of CDATA. In my experience this is more robust to data transports where the encoding is broken - which we have more often than I like to think about here - as it keeps to 7-bit ascii, AND it is better to the human reader as "<", ">" and "&" are only found in their proper form in tagnames and entities and not as a CDATA stream. Also linefeeds etc are encoded as their numeric XML entity, resultning in each log event generating exactly two lines of output (but can be very wide).

We could add a 7-bit transport property (a boolean) to XMLLayout_Blue and if 7-bit transport property were set, your style of encoding would be used.
