This is precisely why schema-awareness was added to the language in XSLT
2.0. If you write your stylesheets to take advantage of schema awareness,
then in many cases you can get compile-time error or warning messages if
your code contains paths that are inconsistent with the input schema, or if
it constructs output that is inconsistent with the output schema.

> 
> Hi everyone -
> 
> I created an XML Schema to validate some XML data, and then 
> created several XSLT stylesheets to transform the data.
> 
> Unknown to me, someone made some changes to the schema and 
> the data, and now the stylesheets I created don't work.
> The stylesheets contain templates that match paths that no 
> longer exist because the schema and the data changed.
> 
> Q: Is there some way to validate, cross-reference, or somehow 
> produce a list of all the valid paths possible in an XML 
> document described by a schema so that I can determine if a 
> path in a template is no longer valid (something similar to 
> when a Java or C compiler gives you a "trying to reference an 
> undeclared variable" error)?
> 
> Thanks for your help.
