[xsl] [XSLT2] setting context inside funcdefs

[Tobias Reif <tobiasreif@xxxxxxxxxxxxx>]

Hi

Inside function definitions, is there a way to set the context to that 
of the function call, so that I can write "local-name()" etc?

Or should I pass in the context node as argument, in addition to all the 
local params visible to the function call.
Then I probably  would write s.th. like 
"local-name($callers_context-node)"; which is more typing ...

"When a stylesheet function is called, the focus within the body of the 
function is initially undefined. [ERR006] When the focus is undefined, 
evaluation of any expression that references the context item, context 
position, or context size results in a dynamic error. The processor must 
signal the error."

" [ERR075] Within the body of a stylesheet function, the focus  is 
initially undefined; this means that any attempt to reference the 
context item, context position, or context size is a dynamic error. The 
processor must signal the error. It is not possible within the body of 
the stylesheet function to access the values of local variables that 
were in scope in the place where the function call was written. Global 
variables, however, remain available."
