[xsl] foreign keys in a xml-database

[ChivaBaba@xxxxxxx]

Hi folks,

does anybody know, whether there is a technique of defining foreign keys in a xml-database by xml or xsl??

I want to avoid redundancies and therefor to store often used elements in a seperate xml-file. The strukture of my main xml-file shall only contain references to the seperately saved elements and not the whole data each time. Is there any posibbility to do so???


Many thanks in advance,

Stefan Greim
