Quick demo on how to apply "Field Definition Rule" on Attachment picker to filter out attachments that dont end with "xls" extension
Attachment picker works on Confluence objects "Attachments" - https://docs.atlassian.com/atlassian-confluence/5.8.6/com/atlassian/confluence/pages/Attachment.html
Which means, we can access ANY property of these objects - such as fileName (as in this example) or labels, via "labelling.label" (which means we call "getLabelling" then call "getLabel" on the underlying objects), or any other "get" method
