[tdf-discuss] Replace "validate" in XML Filter dialog with "Open in Editor"

Hi, 

the XML filter settings dialog contains a test facility for user-defined 
XSLT import and export filters. For the export filters, you can view the 
highlighted source code of the exported XML and then validate the result 
against the given DOCTYPE or schema. 

Instead of offering that validation I'd rather make it possible to open 
the result in whatever editor is registered as defaul for XML in your 
desktop environment. 

First, we're not able to maintain a proper XML catalog anywhere in LibO, 
so for any non-trivial DOCTYPE or schema definition, the validation might 
just fail because the schema or some parts of the schema are not found by 
LibO. 

Second, I've been working on and off on replacing the Saxon/Java based 
transformation service with one based on libxslt, thus removing the Java 
dependency when working with XSLT in LibO. Implementing a validation 
service based on libxslt would require some additional non-trivial (seen 
from my humble C++ coding skills) work, which I'd like to avoid because I 
don't see much value in the built-in validation (see above). 

So I'd like to hear your opinions on that: is anyone using the validation 
button or at least theoretically sees some practical value to it, 
compared to offering to open the resulting XML in your favourite editor? 

Thanks and cheers, 

Peter
