URLs in manual stripped

I have a slight problem with URLs in the manual - specifily, in preface page (preface.xml). The link is written as: <ulink url="&url.php.docs;">&url.php.docs;</ulink> and the entity url.php.docs is: <!ENTITY url.php.docs "http://www.php.net/docs.php"> However, when I build the manual (with DSSSL, phpweb version), the URL comes out as /docs.php - i.e. with host part stripped. Why is it and how can one to make it to put the full URL there? -- Stanislav Malyshev, Zend Products Engineer stas@zend.com http://www.zend.com/ +972-3-6139665 ext.109
