I would argue that being able to pass parameters to the stylesheet is required.
If we dont support this functionality now, then it will need to be added sooner
or later. Some implementations (including eXist-db) already provide a
proprietary function for invoking XSLT from XQuery - e.g.
transform:transform($node-tree as node()?, $stylesheet as item(), $parameters
as element(parameters)?) as node()

At present in eXist-db $parameters is really a constructed node of the form -

<param name="some-name" value="some-value"/>
<param name="other-name"><a/></param-name>

I am not necessarily advocating exactly the same approach, however I do feel
that parameter passing is important. XSLT allows external parameters so we
should really try and support them. The approach could be similar to that used
for fn:serialize in F&O 1.1.
Whilst it could be done by creating some sort of map datatype, do we not
already have enough scope through constructed nodes?
I cannot speak for all implementations or use-cases, but typically the
parameters are smaller than the XSL document itself and as such I would expect
paramaters as constructed nodes to be a more efficient approach than
reconstructing the XSLT as suggested in comment #4.
