Correction: This should have been <xsl:value-of select="..." xmlns:file="..."/> for it to properly invoke the function. I've also discovered that if you want to ensure you are using the version of an assembly you intend to be using, regardless of whether it is in the GAC or not, use the 'from' query string parameter to explicity tell Saxon to "use *this* assembly." For example,

<xsl:value-of
select="file:SaveExternalFile('http://s3.amazonaws.com/m.david/xslt/eveel_plan/XSLnT.png', '/tmp/foo.png')"
    
xmlns:file="clitype:Xameleon.Function.HttpFileStream?asm=Xameleon;ver=1.0.0.0;sn=8974f7aaf62d3d0f;from=/srv/wwwroot/webapp/bin/Xameleon.dll"/>

I've now got this working via an ASP.NET-based application (something in which I didn't have working properly less than an hour ago) which means I'm quite a bit closer to having things buttoned up into a usable "plug-and-play" web application than I thought I was when I wrote the initial response. Still won't be today or tomorrow, but definitely sooner rather than later (like << that really helps nail things down! ;-))
