Aw: Re: [xsl] passing a function as a parameter to transform()

Perhaps try visibility="public" on the function declaration

Thank you!

That moves the error into the stylesheet called by transform():

Engine name: Saxon-EE 10.3 (External)
Severity: error
Description: Cannot find a 1-argument function named Q{data:,dpc}tiny()

The tiny test example has an "outer" stylesheet:

</xsl:stylesheet>

presumably I have not set the parameter up correctly to be recognized as
a function in the stylesheet being called by transform(), but I'm
finding myself at a loss as to how not.

What am I doing wrong, here?

Thanks!
