[oXygen-user] How To Apply Saxon XQuery to Input Document of Transformation Scenario

[Sorin Ristache]

Hello,

I think the XML input document is the default context of an unprefixed 
XPath expression, that is an expression with no $doc/ prefix and with no 
doc('someDocument.xml')/ prefix. You can just omit the . character as 
the first step of an XPath expression applied to the input XML document 
without changing the meaning of the expression. It does not seem to 
represent a special case of XQuery usage or Saxon usage to warrant 
special treatment in a user manual. Am I missing something?


Regards,
Sorin
