OK then yes.

However it depends on how much customisation you want.
If you allow each property to have its own stylesheet then that's a lot 
of power, it could reformat the entire document, and to get that power 
you'd need to do as you say and arrange a processing step that builds 
the stylesheet as required.

however if you want to constrain things more then you could customise 
things based on included input documents rather than stylesheets, eg 
using the collection() function to pull in all xml files in a directory 
them...

make a heading green unless a customisation sets a different color

<xsl:variable name="custom">
  <xsl:copy-of select="collection(....)"/>
</xsl:variable>
<xsl:key name="custom" match="c" use="@x"/>

<xsl:template match="property">
<dt style="color:{
(key($custom,concat(.':color'),$custom),'green')[1]}"
>
<xsl:value-of select="."/>
</dt>


then

<property>foo</property>

will come out as
<dt style="color:green">foo</dt>

unless somewhere in an xml file pulled in by the collection() function 
there is an element of the form

<c x="foo:color">red</c>

in which case

<property>foo</property>

would come out as

<dt style="color:red">foo</dt>

this can work well for simple customisation, but if you start to need 
conditional logic etc, it's probably simpler to go back to allowing full 
xslt, whiich gets you back to where you started.
