The title alone would probably result in a chanting "NO!" as the popular answer, but please let me elaborate.
Background
We have a table of items that represent something. Each item can hold one to five attributes. A column in the table displays how many attributes each item has. This column consists of a cell for each item, containing a link-styled label saying 1, 2, 3..., depending on how many attributes it has. If the user hovers over the cell, a tooltip will appear displaying a text with the ID's of the attributes contained in this item.
Problem
The label, styled as a link, is not clickable as it ignores any click input. The reason for its appearance as a link is to attract the user to it, potentially leading to the user thinking "Hey, I have something here". They might hover over it, perhaps try to click it, and will be shown the tooltip.
I'm not really sure how else to communicate affordance for a tooltip.
Question
Would this be considered good UX? You could argue that the user is being fooled, but is the gain enough to justify that?
Own opinions are OK but I would prefer factual evidence strengthening your case.
EDIT : I guess a side question here is whether it's OK to have a tooltip for something that isn't an action but a display of data instead?


titleattributes notalt:). Only old versions of IE (inappropriately) displayaltas a tooltip, it's meant for accessability – Ben Brocka Apr 18 '12 at 18:39titlesfor imgs too, alt is only for accessability – Ben Brocka Apr 18 '12 at 19:52[alt]attribute is not shown as a tooltip, but the[title]attribute is. The[alt]attribute is required as a textual replacement of the contents of the image in the context of the page, whereas the[title]attribute is meant to be used as the title of the contents. Oftentimes developers will add one, the other, or both with identical text (which is not correct, but common). The differences are akin to the differences between subtitles and closed captions. – zzzzBov Apr 18 '12 at 21:21
