How to used HTML tags with XML/XSL

Hello,
 I build my home page using XML and write XSL file to transform it to
HTML. The problem is that I can't use normal HTML tags (like <br>)
unless specifying it explicitly in the XSL file I make. This will be
hard with tags like <table>. Is there a way to use all HTML tags without
specifying them explicitly.
