The actual value of the pseudo-attribute is the value after each reference is replaced by the character it references. This replacement is not performed automatically by an XML processor.</p> <p>The <code>xml-stylesheet</code> processing instruction is allowed only in the prolog of an XML document. The syntax of XML constrains where processing instructions are allowed in the prolog; the <code>xml-stylesheet</code> processing instruction is allowed anywhere in the prolog that meets these constraints.</p> <blockquote> <b>NOTE: </b>If the <code>xml-stylesheet</code> processing instruction occurs in the external DTD subset or in a parameter entity, it is possible that it may not be processed by a non-validating XML processor (see <a href="#XML">[XML10]</a>).</blockquote> <p>The following pseudo attributes are defined</p> <pre>href CDATA #REQUIRED type CDATA #REQUIRED title CDATA #IMPLIED media CDATA #IMPLIED charset CDATA #IMPLIED alternate (yes|no) "no"</pre> <p>The semantics of the pseudo-attributes are exactly as with <code><LINK REL="stylesheet"></code> in HTML 4.0, with the exception of the <code>alternate</code> pseudo-attribute. If <code>alternate="yes"</code> is specified, then the processing instruction has the semantics of <code><LINK REL="alternate stylesheet"></code> instead of <code><LINK REL="stylesheet"></code>.</p> <blockquote> <b>NOTE: </b>Since the value of the <code>href</code> attribute is a URI reference, it may be a relative URI and it may contain a fragment identifier. In particular the URI reference may contain only a fragment identifier. Such a URI reference is a reference to a part of the document containing the <code>xml-stylesheet</code> processing instruction (see <a href="#RFC2396">[RFC2396]</a>). The consequence is that the <code>xml-stylesheet</code> processing instruction allows style sheets to be embedded in the same document as the <code>xml-stylesheet</code> processing instruction.</blockquote> <p>In some cases, style sheets may be linked with an XML document by means external to the document. For example, earlier versions of HTTP <a href="#RFC2068">[RFC2068]</a> (section 19.6.2.4) allowed style sheets to be associated with XML documents by means of the <code>Link</code> header. Any links to style sheets that are specified externally to the document are considered to occur before the links specified by the <code>xml-stylesheet</code> processing instructions. This is the same as in HTML 4.0 (see <a href="http://www.w3.org/TR/REC-html40/present/styles.html#h-14.6">section 14.6</a>).</p> <p>Here are some examples from HTML 4.0 with the corresponding processing instruction:</p> <pre><LINK href="mystyle.css" rel="style sheet" type="text/css"> <?xml-stylesheet href="mystyle.css" type="text/css"?> <LINK href="mystyle.css" title="Compact" rel="stylesheet" type="text/css"> <?xml-stylesheet href="mystyle.css" title="Compact" type="text/css"?> <LINK href="mystyle.css" title="Medium" rel="alternate stylesheet" type="text/css"> <?xml-stylesheet alternate="yes" href="mystyle.css" title="Medium" type="text/css"?></pre> <p>Multiple <code>xml-stylesheet</code> processing instructions are also allowed with exactly the same semantics as with <code>LINK REL="stylesheet"</code>. For example,</p> <pre><LINK rel="alternate stylesheet" title="compact" href="small-base.css" type="text/css"> <LINK rel="alternate stylesheet" title="compact" href="small-extras.css" type="text/css"> <LINK rel="alternate stylesheet" title="big print" href="bigprint.css" type="text/css"> <LINK rel="stylesheet" href="common.css" type="text/css"></pre> <p>would be equivalent to:</p> <pre><?xml-stylesheet alternate="yes" title="compact" href="small-base.css" type="text/css"?> <?xml-stylesheet alternate="yes" title="compact" href="small-extras.css" type="text/css"?> <?xml-stylesheet alternate="yes" title="big print" href="bigprint.css" type="text/css"?> <?xml-stylesheet href="common.css" type="text/css"?></pre> <hr title="Separator from footer"> <h2> <a name="References"></a>A References</h2> <dl> <dt> <a name="HTML">HTML40</a> </dt> <dd>World Wide Web Consortium. <i>HTML 4.0 Specification.</i> W3C Recommendation.
