It is not added to every DTD. It is added to DTDs for those applications that want xml:space. Many XML applications do not see a need for xml:space and happily leave it out. Valid documents written in these xml:space ignorant applications cannot use xml:space. Secction 2.10 of the XML spec states, "A special attribute named xml:space may be attached to an element to signal an intention that in that element, white space should be preserved by applications." Note *may* be attached, not "must be attached" or even "should be attached". xml:id would be exactly the same. Use it if you want. Ignore it if you don't. -- +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@m... | Writer/Programmer | +-----------------------+------------------------+-------------------+ | The XML Bible, 2nd Edition (Hungry Minds, 2001) | | http://www.ibiblio.org/xml/books/bible2/ | | http://www.amazon.com/exec/obidos/ISBN=0764547607/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://www.cafeaulait.org/ | | Read Cafe con Leche for XML News: http://www.ibiblio.org/xml/ | +----------------------------------+---------------------------------+
