Using ig:slot with unusual parameters

I'm working on ig:slot features with a ComponentPage. The invoker  
associated to ComponentPage is  
org.infoglue.deliver.invokers.ComponentBasedHTMLPageInvoker (it is  
standard infoglue configuration).
Into org.infoglue.deliver.invokers.ComponentBasedHTMLPageInvoker line  
1714, we can find the process of slot. What is interesting is the list  
of param you can use :
- inherit
- disableAccessControl
- allowedComponentNames
- disallowedComponentNames
- allowedComponentGroupNames
- addComponentText
- addComponentLinkHTML
- allowedNumberOfComponents

I found the parameters allowedNumberOfComponents and  
allowedComponentGroupNames really cool =) You should had it to the  
documentation of ig:slot.

Anyway, my point is : there is a limitation with the ig:slot.
The analysis process works with indexOf " PARAM" with some parameters.  
As you can see, there is a white space befiore param name. I used to  
do tab to delimit my parameter, like this :
<ig:slot
	id="tiles_doc"
	inherit="true"
	allowedComponentGroupNames="layout"
	allowedNumberOfComponents="1"
 ></ig:slot>

With that declaration, allowedComponentNames, disallowedComponentNames  
and allowedComponentGroupNames can't be defined (because of the white  
space into the analysis process).

You can fix it by doing :
<ig:slot id="tiles_doc" inherit="true"  
allowedComponentGroupNames="layout" allowedNumberOfComponents="1"></ 
ig:slot>

So, it isn't really a bug, but it would be better if we could write  
the way we want.
Removing the white space for the few mistaken parameters is simple :
change
	int allowedComponentGroupNamesIndex = slotString.indexOf("  
allowedComponentGroupNames");
into
	int allowedComponentGroupNamesIndex = slotString.indexOf("  
allowedComponentGroupNames");

There are quite a few classes that do the analysis :
- /infoglue2971/src/java/org/infoglue/deliver/controllers/kernel/impl/ 
simple/PageEditorHelper.java
- /infoglue2971/src/java/org/infoglue/deliver/invokers/ 
AjaxDecoratedComponentBasedHTMLPageInvoker.java
- /infoglue2971/src/java/org/infoglue/deliver/invokers/ 
ComponentBasedHTMLPageInvoker.java
- /infoglue2971/src/java/org/infoglue/deliver/invokers/ 
DecoratedComponentBasedHTMLPageInvoker.java

I guess all invoker are not used, in fact I hope so =)
