RE: [xsl] imbedding xsl stylesheet within xml doc ???

One more stupid question, BTW, a big hearty thank you to everyone who
has answered my questions (:

Extracted from the web site:

************************************************************************
*************************
2.7 Embedding Stylesheets
Normally an XSLT stylesheet is a complete XML document with the
xsl:stylesheet element as the document element. However, an XSLT
stylesheet may also be embedded in another resource. Two forms of
embedding are possible:

the XSLT stylesheet may be textually embedded in a non-XML resource, or
the xsl:stylesheet element may occur in an XML document other than as
the document element.
To facilitate the second form of embedding, the xsl:stylesheet element
is allowed to have an ID attribute that specifies a unique identifier.

NOTE:In order for such an attribute to be used with the XPath id
function, it must actually be declared in the DTD as being an ID.

The following example shows how the xml-stylesheet processing
instruction [XML Stylesheet] can be used to allow a document to contain
its own stylesheet. The URI reference uses a relative URI with a
fragment identifier to locate the xsl:stylesheet element:

<?xml-stylesheet type="text/xml" href="#style1"?>
<!DOCTYPE doc SYSTEM "doc.dtd">
<doc>
<head>
<xsl:stylesheet id="style1"
                version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                xmlns:fo="http://www.w3.org/1999/XSL/Format";>

What does the following note mean:

NOTE:In order for such an attribute to be used with the XPath id
function, it must actually be declared in the DTD as being an ID.

BTW I seem to be geting duplicate emails from this list, can someone
please tell me how to squelch the "dup" ?????

Thanks for the response !!!

>>I'm not sure how widely supported this feature is, or how widely used

Heck Why not It seems to me that most style sheets by their very nature
are going to be "specific"

>>where the stylesheet is completely specific to that document; in  this
case I find it eases maintenance to keep the
>>stylesheet embedded within the document

Hey, I wonder if this same technique could be used to imbed the schema
for an xml doc within the doc itself ?????

NOTE:A stylesheet that is embedded in the document to which it is to be
applied or that may be included or imported into an stylesheet that is
so embedded typically needs to contain a template rule that specifies
that xsl:stylesheet elements are to be ignored.

How do you write the template rule to ignore the "xsl:stylesheet
element" ???

I don't think the XSLT 1.0 spec uses either of the terms "imbed" or
"processor statement" so I'm not sure why you put them in quotes.

But section 2.7 of the spec does discuss how a stylesheet may be
embedded in a source document, and gives an example:

http://www.w3.org/TR/xslt#section-Embedding-Stylesheets

I'm not sure how widely supported this feature is, or how widely used.
It works in Saxon, and I've got one situation where I use it myself: a
one-off document with its own stylesheet, where the stylesheet is
completely specific to that document; in  this case I find it eases
maintenance to keep the stylesheet embedded within the document. (And it
gives me a test case, of course!).
