I am sorry.

Actually "xmlto" uses xmllint. For me xmllint produces the same error as 
mentioned in the previous e-mail.

I've put the minimum number of files (that represent the organization of my 
document) with minimum file-contents that produces the error (I hope I can 
attach a 4KB file). Just unpack it and run "make" to validate it.

Note: I've included my entities.xml file intact, in case someone finds it 
useful.

Thank you,
Giannis
