/html/body/div/table/tr/td/a{this is a link}

No, the XPATH syntax doesn't allow to embed comments within the path string.
This is typically not a significant limitation because paths are usually short and a comment can be placed nearby, in the particular syntax of the host language (XSLT, C#, whatever...)
Not a comment syntax, but you can give string literals as predicate, which evaluates as true (imho) and should not change the outcome of the expression. I don't know if this has big performance drawbacks.
/html/body/div/table["this is"]["a table"]/tr/td/a["this is a link"]
But like mjv said, I also would stick to the syntax of the host language.
