why is current rating often left out of transformer data sheets?

I am trying to find a transformer but I often and seeing that the data sheet does not include a current rating. For example this is the entire data sheet of a transformer I was looking at. They have no saturation current and no "how hot this will get given a specific current". I feel as though I am missing something because it is a very common occurrence. like am I supposed to just use the winding resistance?
thank you

What tyoe of transformer is it? I would certainly expect to see a current rating on a power transformer, which this does not appear to be.

"Common occurrence"? I have found the complete opposite, I buy small PCT transformers from Digikey often, and the brands I have purchased there up to now have included the Va value.
Reliable manuf always do, I have found.
