Yes, any of the HTML 5 attributes can be used, for example:
Less:
[data-logged-in="false"]
[data-logged-in="true"]
[data-template*="name"]
[data-template="template_name"]
[data-type="type"]
[data-container-key="node-ID"]
[data-content-key="thread-ID"]
They can be further refined by joining attributes without a comma:
Less:
[data-template="template_name"][data-type="type"]
Or made to apply to multiple attributes with a comma:
Less:
[data-container-key="node-ID"],
[data-content-key="thread-ID"],
[data-type="type"]
