Hola a todos, Rosa:

Some time ago i've developed a way to do simple interations with no
recursivity, only valid for short numbers of iterations  useful for  i.e
months..

This can be easily modified to do a bunch of other things..

You can use a external generated document for big interations, but it's
not very performant, i think, 2 parses...

Perhaps somebody finds that useful..( at least it's usefull for me :)

My 0.02 ? ( nothing compared to the income i've got from the xsl-list :)

Saludos ,
Ignacio J. Ortega

PS.:( this adapted from my code, i've not tested it , sorry if it
contains any errors )
