> Remove support for attribute splitting in XMLConfiguration

> Key: CONFIGURATION-505
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-505
> Project: Commons Configuration
> Issue Type: Improvement
> Affects Versions: 1.9
> Reporter: Oliver Heger

>
> Currently {{XMLConfiguration}} allows setting multiple values for an
> attribute node. (This is possible through the {{Configuration}} interface,
> but of course not supported by XML.) When saving the configuration it tries
> to encode the list as a comma-separated string. On reloading, such strings
> are split again.
> The implementation of this feature is pretty complex because points like
> escaping delimiter characters have to be taken into account. I doubt that it
> works in a reliable way in all possible constellations. OTOH, I don't think
> that this functionality provides much value to users.
> This ticket is about removing this feature. It will still be possible to add
> and query multiple values of an attribute as long as the configuration is in
> memory. When saving, attribute values are checked. If there are multiple
> values, an exception is thrown.
