The initial screeners ( people or software) of resumes look for keywords. So put in all those keywords that you think are relevant even if from a skill perspective they are trivial. For example basic skills related to xml are easily learnt by most developers in a very short time. Ideally no employer should ever be asking for 'xml' skills but they do. So, in this example that I gave, make sure that you put the 'xml' keyword in your resume.
