Re: [xbiblio-devel] CSL proposal

[Johan K. <joh...@gm...>]

At first glance this seems unnecessary to me. I guess it should be  
possible to test wether you would get a result from a macro by using  
an if-tag with the required attributes needed to build the macro. He  
showed that in his example by testing in the if-tag for the issued  
variable. I do not find his second snippet easier to read, more  
confusing actually. I wonder if there are any situations were this is  
really needed or cannot be done with current CSL. I'll be all for it  
if I he can show us an example of something that cannot be done  
currently.

Btw, a use-this-alternate-macro-when-this-macro-or-group-returns-an- 
empty-string attribute could possibly cause an infinite loop,  
especially when added to the macro-tag. That said, I do think it is  
not necessarily out of the question to put this in. I can see where it  
could be less verbose at times. But I am not sure it if is really that  
important to add it.

Infinite loop situation:

<macro name="foo" if-empty-use-macro="bar">
    ...
</macro>


<macro name="bar" if-empty-use-macro="foo">
    ...
</macro>

Btw, Bruce, you didn't respond to my et-al mail of yesterday anymore.  
Just wondering what your answers would be.

Johan
