Good Morning Christian,

Yes, I was wondering if you had received my mail. This time lapse is so not like you.

Thanx for having a look. It would be great if this worked, implementing inheritance-like structures would be so much more transparent.

Have a look at the attachment if you like. Recursion here does not work and a work-around would brake down the systematic approach.

Best,

Rob

Hi Rob, sorry, I’ve just discovered your mail in the basex-talk archive. I believe that the given query should not raise an error as the variable does only reference your function. Let’s see what we can do. – Best, Christian

Hi,

The code[1] below and send as attachment generates a error message: “Static variable depends on itself: $Q{http://www.w3.org/2005/xquery-local-functions}test”.

I use these variables to refer to my private functions in my modules so I can easyly refer to them in a inheritance situation.

It’s not a big problem for me but I was wondering if the error-triggering is justified or that it should work.

[1]===========================================

declare variable $local:test := local:test#1 ;

declare %private function local:test( $i) { if ( $i > 0) then $local:test( $i - 1) } ;

$local:test( 10)

===========================================

Kind regards,

Rob Stapper
