TYPO3 Core

It seems that it is not possible to set a TYPO3 version as suggestion.

Following works:
----------------
'constraints' => array(
'depends' => array(
'typo3' => '4.6.0-0.0.0',
'extbase' => '',
'fluid' => '',
),
'conflicts' => array(
),
'suggests' => array(
'extbase_dam' => '',
),
),
------------

and states:
The running TYPO3 version (4.5.0) is lower than required (4.6.0).

but following doesn't work:
-------------------
'constraints' => array(
'depends' => array(
'extbase' => '',
'fluid' => '',
),
'conflicts' => array(
),
'suggests' => array(
'typo3' => '4.6.0-0.0.0',
'extbase_dam' => '',
),
),
-------------------

as it reproduces: Extension "typo3" was not available in the system. You may want to import it from the TYPO3 Extension Repository.

sometimes extensions are working better under special versions (e.g. a current one) but still support older branches as kind of fallback
