This is an issue. The {{xml:space}} applies only to the configuration section of a plugin. The issue you seem is caused by [this|https://github.com/codehaus/modello/blob/b793290837a55107ee2e8f2a3015aedc01db3156/modello-plugins/modello-plugin-xpp3/src/main/java/org/codehaus/modello/plugin/xpp3/Xpp3ReaderGenerator.java#L796]. Search also [here|https://codehaus-plexus.github.io/modello/modello.html] for {{trim}}. There is regression concerning Modello because the trim existed in [Modello code for nine years|https://github.com/codehaus/modello/blame/b793290837a55107ee2e8f2a3015aedc01db3156/modello-plugins/modello-plugin-xpp3/src/main/java/org/codehaus/modello/plugin/xpp3/Xpp3ReaderGenerator.java#L796].

>                 URL: https://issues.apache.org/jira/browse/MNG-6175
>             Project: Maven
>          Issue Type: Bug
>          Components: Plugin API
>    Affects Versions: 3.3.9
>            Reporter: Jesko Jochum
>            Priority: Minor
>
> Leading and trailing whitespaces in the "pom.xml" get deleted.
> Exemplary excerpt of a "pom.xml" file:
> ...
> <properties>
> <batch.sortId xml:space="preserve"> 1 </batch.sortId>
> </properties>
> ...
> Checking the "effective pom" results in:
> ...
> <properties>
> ...
> <batch.sortId>1</batch.sortId>
> ...
> </properties>
> ...
> So the leading and trailing whitespaces have been deleted. [MNG-5380] states this to be resolved since version 3.0.4.
