The Welcome Message text resource is configured to show an English message if the English skill-tag is selected, and a German message if German is selected
All of this markup will be replaced with the message contained in between <tag> and </tag>, and any other tagged sections will be removed, when rendered and delivered to the seeker/agent
If there is no skill tag selected, or a skill tag is selected that doesn't match anything in the text resource, then the first tagged section will be used as a fallback
For example, if I picked Dutch as the skill-tag, then the English resource would be sent to me in the welcome message, because it is first
If there is some text that is not contained in the <tag></tag> blocks, it will always be rendered. Not sure we would ever want to do that, but that is how it would work
If there aren't any skill-tag sections defined, then the text resource will behave as it has done before.
