## Default Slot
The first element inside the component which is not a named slot will
be considered the `default` slot. For example:

## Slot scopes
For other kind of advanced use cases, the content of a slot may depends on some
specific information specific to the generic component. This is the opposite
of the slot params.
For other kinds of advanced use cases, the content of a slot may depends on some
information specific to the generic component. This is the opposite of the slot
params.
To solve this kind of problems, one can use the `t-slot-scope` directive along
with the `t-set-slot`. This defines the name of a variable that can access
everything given by the child component:
```xml
<div>
<MyComponent>
<t t-set-slot="foo" t-slot-scope="scope">
content
<t t-esc="scope.bool"/>
<t t-esc="scope.num"/>
</t>
</div>
</MyComponent>
```
And the child component that includes the slot can provide values like this:
```xml
<div>
<t t-slot="foo" bool="other_var" num="5">
</div>
<t t-slot="foo" bool="other_var" num="5">
```
In the case of the default slot, you may declare the slot scope directly on the
component itself:
```xml
<MyComponent t-slot-scope="scope">
content
<t t-esc="scope.bool"/>
<t t-esc="scope.num"/>
</MyComponent>
```
