RE: XSLT 2.0 dynamically parameterized output? Was: Re: Trying to use Docbook transforms with Saxon7

In XSLT 2.0, an <xsl:output> specification may be named, and
<xsl:result-document> has a format attribute to reference a named
<xsl:output> declaration. You can select an output format dynamically,
but it is not possible to calculate the values of the individual
serialization parameters dynamically.

Recommended version of Saxon for DocBook XSL stylesheets is Saxon

DocBook stylesheets are written in XSLT 1.0 with lots of EXSLT and 
vendor dependant extensions. These extensions are not 
always available 
in Saxon7 as similar functionality is provided by XSLT 2.0.

Yes, I know and I had no trouble running the stylesheet in 
Saxon 6.5.2. 
But this doesn't help me get it running in Saxon 7.

The Doctype chunker.xsl stylesheet is using saxon:output, 
exsl:document, 
etc. for their ability to dynamically specify the output 
parameters with 
attribute value templates.

There seem to be two main differences between these extension 
instructions and xsl:output/xsl:result-document provided by XSLT 2.0:

1. xsl:output may only appear at the top level.
2. (Serious problem) none of xsl:output's attributes are specified in 
the syntax summary as allowing attribute value templates.

So what does one use in 2.0 when it is desired to dynamically 
calculate 
values of, e.g., doctype-system, media-type, etc.?
