I assume he's already using that.

The problem is that TM uses the rule which gives the longest match.  
The HTML grammar has a specific rule for the <%#...%> case (since the  
Ruby syntax doesn't know about erb and would include %> in the comment).

This rule will always be a longer match than the begin = "<%" in the  
ASP grammar (since for begin/end rules, the length of the begin  
pattern is used), thus the Ruby comment rule (in the HTML grammar)  
will win over the embedded ASP rule, in the ASP grammar which  
includes the HTML grammar.

This is one of the reasons why I recently proposed to change the  
system to always use the first rule which matches, rather than the  
longest :)

For now I'd suggest just removing the Ruby comment rule from the HTML  
grammar, and hopefully soon I'll change the precedence algorithm (I  
need to check and possibly re-arrange all grammars when doing so).
