Using Expressions/PropertyPlaceholders in blueprint xml

[real_thuri <re...@gmx.de>]

Hello,

i need to get the version of the bundle which contains the blueprint xml 
as a value.
I hoped to get it like this ${bundle.version} or ${blueprintBundle.version}

I need the value to use in another expression, like this
<argument name="expression" value="component.version==${bundle.version}" />

Do you have any idea how a could to this?

Regards,
Michael
