Re: [xsl] Why does Chrome's XSL processor validate my XML files when processing them, and how can I make it stop doing that so that it processes them faster?

["Kurt Cagle kurt.cagle@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I use the XML Tree extension for Chrome (
https://chrome.google.com/webstore/detail/xml-tree/gbammbheopgpmaagmckhpjbfgdfkpadb?hl=en).
Not only does it color code the output and allow for collapsing sections,
but I suspect it disables the schema parssing.that the Chrome native
processor uses.
