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.
