By informing themselves of how user agents will handle each of them in 
practice. How the spec says they should be used is one thing and how 
vendors choose to apply a specification is another. So for example by 
understanding how a screen reader user may deal with @alt contents, or 
how useful the title element is to a screen reader user, the author is 
in a better position to make a judgement call on how they should be 
applied in any given situation. Of course these are examples that relate 
to assistive technology but correct use of @alt and a good title element 
can have an impact in other domains such as SEO. There are also a wider 
variety of UAs to consider, but the principle is the same. How will the 
UA deal with this code and how will this then be of value to the end 
user. The world of web development is full of adjusting to these kinds 
of behaviours.
