[HELP]indent can not be multiply defined at the same import level! Old value = no; New value = yes

[Ruedi Anneler]

Description:org.apache.cocoon.ProcessingException: Exception in creating Transform Handler: javax.xml.transform.TransformerException: indent can not be multiply defined at the same import level! Old value = no; New value = yes   I see that there's something wrong, but that's all. I don't have any idea what this message is talking about. I don't know what it is talking about and WHY, and, more important, what i must DO to correct this error.   Hmmm....., I wonder wheter it's a good idea to tell people what's wrong instead of telling them what to do to get it up and running ;-).   Please help. Thanx.
