[REBOL] func question

[norsepower]

I created the following function for joining the information necessary 
to display a web page image in HTML.

display|image: make function! [ src text.align alt ] 
        [ rejoin {<IMG SRC="} src {" Align=} text.align { ALT="} alt {"
>} ] 


My question is, if I choose to use the words in block [ src text.align 
alt ] in any other function or anywhere else in the script, could there 
be a conflict in values?  Or do the values in a function remain 
entirely within the function?

Thanks.
