Support methods on actions

[ssire]

Oppidum command's analyser does not allow to declare methods on actions.

For instance if an item supports an action "administrate" (e.g. to bring up a form to administrate an item) :

    <action name="administrate" epilogue="standard">
      <model src="modules/company/administrate.xql"/>
      <view src="modules/company/administrate.xsl"/>
    </action>

It is not possible to define (e.g. to manage form submission) :

    <action name="administrate" method="POST" epilogue="standard">
      <model src="modules/company/administrate.xql"/>
      <view src="modules/company/administrate.xsl"/>
      <action name="POST">
        <model src="modules/company/administrate.xql"/>
        <view src="modules/company/administrate.xsl"/>
      </action>
    </action>

However that would be sound since that limitation imposes to create a "fake" item to receive submitted data or to explicitely retrieve and test the method with code such as let $m := request:get-method() inside the XQuery model script handling the action.

A complement to that issue is that it is also not possible to define at the mapping level the fact that an action is only compatible with a restricted set of HTTP VERBs (for instance an action that only accept POST requests).

A potential solution would be to support the supported attribute on the action element, with the same issue as Issue #17
