I cannot edit .XML files uploaded to the control room (private workspace) in A360. However, I can edit .TXT files. Is this by design? How should you edit .xml files that are bot dependencies?

You should be able to edit xml files as well, make sure the tags are properly opened and closed, if it is a invalid xml then it won't let you save the file.

On further investigation, the AA Workspace doesn't handle comments as expected. For instance:

This is "Valid" in the AA Workspace:

<!--

This is a comment,

possibly multiline.

-->

<gomer></gomer>

Whereas this is not valid:

<!-->

This is a comment,

possibly multiline.

<-->

<gomer></gomer>

While most XML formatters (and indeed, the formatter used by the view in the AA workspace) identify the second example above as valid, AA does not.
