Because that's how xml namespaces work. <html xmlns:py="http://purl.org/kid/ns#"; xmlns="http://www.w3.org/1999/xhtml"; py:extends="sitetemplate"> Includes 2 definitions: the xhtml namespace (http://www.w3.org/1999/xhtml) which is given no prefix and the kid namespace (http://purl.org/kid/ns#) which has the prefix "py". Very loosely you can compare this to importing python modules: from xhtml import * import kid as py You example snippet then has one tag and one attribute (excluding the xmlns attributes) -- the tag is "html" which is in the default (i.e. XHTML) namespace, and the attribute is "py:extends" which is in the kid namespace (note that, just like in the python pseudocode the use of "py" as the prefix is entirely arbitary; you could use "kid" or "ihgsdfi" or whatever, as long as you're consistent). Now compare your replacement example: <html xmlns="http://purl.org/kid/ns#"; py:extends="sitetemplate"> You now have an tag "html" in the kid namespace as an unknown namespace prefix "py". That's why you have problems. > Also, why does URL end with a #? What does # do? Because the full string, including the "#" is the URI for the kid namespace. There's no intrinsic reason for the # but it needs to be included to correctly identify the kid namespace. -- "The universe doesn't care what you believe.
