Thank you. I ran into a some problems using the new one at https://logging.apache.org/xml/ns/. Here is a simple `log4j2.xml`: ```xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Configuration> <Configuration xmlns="https://logging.apache.org/xml/ns"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="https://logging.apache.org/xml/ns https://logging.apache.org/xml/ns/log4j-config-2.xsd"; status="WARN"> <Properties> <Property name="root.logging.level">${sys:myapp.root.logging.level:-${sys:rootLogger.level:-WARN}}</Property> </Properties> <Appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="%date{ABSOLUTE} %class %method - %message%n%throwable" /> </Console> </Appenders> <Loggers> <Root level="${root.logging.level}"> <AppenderRef ref="Console" /> </Root> </Loggers> </Configuration> ``` The new XSD incorrectly points out two problems: 1. It doesn't like the way I've set the value for a Property: as content. However, that is one of the ways shown in the example at https://logging.apache.org/log4j/2.x/manual/configuration.html#concise-syntax. Currently, it will only validate if I set the value using the `value` attribute. 2. More significantly, it does not accept "${root.logging.level}" for Root's `level`, which is using [Property Substitution](https://logging.apache.org/log4j/2.x/manual/configuration.html#PropertySubstitution). Note that the use case for the way I've written the above configuration is that if I start my Java Virtual Machine with `-Dmyapp.root.logging.level=DEBUG` (or some other level), it will use that for the root logger if it is set, otherwise it defaults to WARN. -- This is an automated message from the Apache Git Service.
