If your program validates the XML against the DTD during normal execution, then you should just get the DTD from wherever your program will get it.
If not and the DTD is extremely short (only a few lines), then storing it as a string in your code is probably okay.
Otherwise, I'd put it in an external file and hav... |

I think cursors get a bad name because SQL newbies discover them and think "Hey a for loop! I know how to use those!" and then they continue to use them for everything.
If you use them for what they're designed for, I can't find fault with that. |
SQL is a set based language--that's what it does best.
I think cursors are still a bad choice unless you understand enough about them to justify their use in limited circumstances.
Another reason I don't like cursors is clarity. The cursor block is so ugly that it's difficult to use in a clear and effective way.

The basic issue, I think, is that databases are designed and tuned for set-based operations -- selects, updates, and deletes of large amounts of data in a single quick step based on relations in the data.
