As Tedster wrote, the transition from 4.01 to xhtml is fairly straightforward. You can write a site in 4.01 and prepare it for eventual conversion to xhtml by observing the following:

Validate your code to the current doctype

Close and properly nest all tags

Structure page content with headings, paragraphs, and lists

Write all tags in lower case

Enclose attributes in double quotes

Use CSS for formatting
