Would it be wrong for a basic processor to handle (more specifically,
not complain about) validation = "lax" ?  This would make it slightly
easier to write transforms that run in both basic and schema-aware

For example, then you could do:

<xsl:import-schema ....

<xsl:document validation="lax">  (or collection(.... ?validation=lax)

<xsl:result-document validation="lax">

...and run it using a basic processor.  At the moment, the basic
processor (Saxon in this case) will state that you need a schema-aware
processor to use the validation attribute - but when its set to "lax"
it should be fine and just operate as if no schema definition is

As it stands, you need to double up and use use-when a lot, but I
think it should be possible to set everything to lax and just put
use-when on the import-schema elements.

The benefit would be a simple way of developing/testing with
schema-awareness and running without it, or passing around a
stylesheet without the need to pass around the schemas with it (both
of which depend on the behaviour of the stylesheet not changing on
whether the input is typed or not).
