in mpdialog mode, we just write out some JavaScript to display

dialog to the reader asking whether they want to install MathPlayer

Depending on the response we get, we then instantiate an XSL processor

and reprocess the doc, passing $secondpass according to the
|
|
reader response.

<h:p>Using d-o-e is fairly horrible, but this code is only for IE

anyway, and we need to force HTML semantics in this case.</h:p>

<h:h2>IE5XSL stylesheet</h:h2>
|
|
<h:p>In a rare fit of sympathy for users of
|
|
<h:em>the-language-known-as-XSL-in-IE5</h:em> this file incorporates a
|
|
version of the above code designed to work in the Microsoft dialect.
|
|
This is needed otherwise users of a MathML rendering behaviour would
|
|
have to make a choice whether they wanted to use this stylesheet
|
|
(keeping their source documents conforming XHTML+MathML) or to use
|
|
the explicit Microsoft Object code, which is less portable, but would
|
|
work in at least IE5.5.</h:p>
|
|
|
|
<h:p>This entire section of code, down to the end of the stylesheet is
|
|
contained within this ie5:if. Thus XSLT sees it as a top level element
|
|
from a foreign namespace and silently ignores it. IE5XSL sees it as
|
|
"if true" and so executes the code.</h:p>
|
|
|
|
|
|
<h:p doc:ref="closecomment">First close the comment started at the beginning. This ensures
|
|
that the bulk of the XSLT code, while being copied to the result tree
|
|
by the IE5XSL engine, will not be rendered in the browser.</h:p>
|
|
|
|
<h:span doc:ref="eval">Lacking attribute value templates in
|
|
xsl:element, and the local-name() function, we resort to constructing
|
|
the start and end tags in strings in javascript, then using
|
|
no-entities attribute which is the IE5XSL equivalent of disable-output-encoding</h:span>
