Creating Mxml Component Files - MACROMEDIA FLEX BUILDER-USING FLEX BUILDER Use Manual

If the namespace contains several components that you want to insert in the file or if you want
to insert several instances of the same custom component in the file, you can specify the
namespace once in the Application tag and omit it from each component tag, as follows:
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
xmlns:xyz="assets.components.controls.*">
<xyz:myComboBox />
<xyz:myButton />
</mx:Application>

specified by the component's class package. For example, suppose you want to insert a Flash
component called foo.swc that belongs to the my.comps.foo class. The namespace is as follows:
xmlns:xyz="my.comps.*"
For more information, see "About SWC files" in Developing Flex Applications Help.
