Log4j2 Appender attributes with strict xml config
Hi,
I'm using log4j2-beta9 and want to configure it using a log4j2.xml in strict
mode. My issue is: how do I specify attributes that are not in the shipped
schema file? An Example:
?xml version=1.0 encoding=UTF-8 ?
Configuration
status=DEBUG
strict=true
monitorInterval=5
name=TestingAttributes
verbose=true

Notice that I want to set the appender to have the target SYSTEM_ERR but the
attribute is not allowed in strict mode.
target=SYSTEM_ERR !-- cvc-complex-type.3.2.2: Attribute 'target' is not

I could always edit the Log4j-config.xsd and allow that attribute there but
that would be kind of wrong also because not all appenders have a target
attribute.
As searching the web didn't help me so far, I'm asking you: Is there anything

Re: Log4j2 Appender attributes with strict xml config
Alexander ,
XML validation against the XML Schema is not fully baked because the
Log4j 2 XML Schema is incomplete. Due to the current dynamic nature of
the configuration file (it's schema is tied to the Java code and the
annotations used), we need to generate the XML Schema based on these
annotations in the same way that the annotations are currently
processed to create the metadata configuration.
Simone had proposed a different to do configuration, but that has not
gone anywhere yet, and I am not sure it dealt with XML validation.

AW: Log4j2 Appender attributes with strict xml config
So basically when you want strict validation you want it really strict, i.e.
not only for the base types like appenders, filters but also their attributes?
As far as I understand that would result in a bigger schema where each type is
defined in the schema and the config looks more like the non-strict version.
User supplied types would be impossible then, unless they are defined as a
generic type in the schema which allows for KeyValuePairs or such (like I did
in the edited schema below).
Best Regards,
Alex

Re: Log4j2 Appender attributes with strict xml config
The current idea I have is that the XML Schema would reflect exactly
the code that is running. We should start with that. AFAIK, the
current code we have does not allow open-ended XML fragments, but I
could be wrong...

I should have been more specific, or there is another piece I do not understand. If I or Alexander provide our own Appender, they will be annotated with Log4j2 annotations. Today, yes, the XML is open-ended, but not per XML Schema. In my imaginary yet-to-be-implemented system, you would tell Log4j, at developement or build time of your app, to rebuild the metadata such that: (1) the normal config knows about my custom appender, and (2) I can generate a new XML Schema.
