The short answer is: I didn't want to be tied to Perl; AppML can generate code in any programming language. (Although Perl is the first one.)

Here's AppML output: 

nferraz@debian:~/appml$ ./appml.pl xml/sample.xml

As you can see, the source metafiles are divided in directories: These metafiles are nothing more than text templates, used to generate code; if I wanted to generate Java code, I would probably create a new directory to store Java metafiles.
