BLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
(Note: There seems to be a minor typo in your original string — it should likely end with ".dtd" instead of ".d". I've corrected it here for proper context.)
If you actually refer to a declaration in an XHTML document, it would look like this:
```html
```
This is a standard DOCTYPE declaration for XHTML 1.0 Transitional documents.
