Why it is an enhanced filter:

Major enhancement is done on the lang block processing algorithm. The actual algorithm
supports nested tags that may mark language c ontent or other text formatting
aspects. The standard algorithm fails to deal with several nested tags,
because of the nesting effect on a single RegExp fetch ahead.

The enhanced algoithm is aware fo span nesting and will correctly fetch ahead the
actual corresponding closing tag for the language block start marker.

When using the old syntax, with tag, a standard single regexp fetch ahead is performed.

Other changes:

This filter processes the lang blocks one by one, eliminating all unwanted (non matching)
languages.

Todo:
Check wether a default language version feature can be added back.

To Install it:
- Enable if from "Administration/Filters".

To Use it:
- Create your contents in multiple languages.
- Enclose every language content between:
Hello!
This text is common for every language because it's out from any lang block.
Bye!

- Will print, if current language is English:
Hello!
This text is common for every language because it's out from any lang block.
Bye!

- And, in Spanish, it will print:
Hola!
This text is common for every language because it's out from any lang block.
