It's certainly not allowed at the moment:
[ERR XTSE1660] A basic XSLT processor must signal a static error if the
stylesheet includes an [xsl:]type attribute, or an [xsl:]validation or
default-validation attribute with a value other than strip.
But it seems a reasonable idea. Raise it on the W3C bugzilla.

Subject: [xsl] basic processors handling validation lax
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 processors.
For example, then you could do:
<xsl:import-schema ....
use-when="system-property('xsl:is-schema-aware')='yes'"/>
<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 available.
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).
