Hi, Mark,

that's actually for telling ESQL which database you have. Postgres and MySQL 
have an explicit limit clause while most other vendors (very unfortunately) 
don't have such clauses. It goes hand-in-hand with the max-rows and skip-rows 
settings.

You can use the following values:

mysql, postgres, jdbc, auto (IIRC - please crosscheck)

"mysql" uses the native mysql limit clause
"postgres" the postgres clause
"jdbc" uses what is possible with jdbc (let's the vendor driver do the work)
"auto" tries to find the correct one (IIRC from the driver url)

I know is quite out of date...

Well, we didn't add them yet (easy like that ;-) ...but seriously

They *should* be in there but... you know... documentation... none of the 
developers wants to do it ;-) 

I fear the xsd could be quite out of date.

But feel free to ask :-)

Cheers
