Did you run into a specific problem forcing the translation of . to -? 
The HTML spec says:
- ID and NAME tokens must begin with a letter ([A-Za-z]) and may be 
followed by any number of letters, digits ([0-9]), hyphens ("-"), 
underscores ("_"), colons (":"), and periods (".").

The XHTML spec seems to be even more open, allowing many many 
characters to be used in names. It says you should only use names 
matching [A-Za-z][A-Za-z0-9:_.-]* if you want to be compatible with 
HTML4.
