+# Expose internal component as host
+
+## Summary
+
+Allow dynamic components to expose internal element so all attributes, id and classes will apply directly to them instead of the host element.
+
+## Motivation
+
+It will allow to reduce boilerplate in configuration of dynamic components because standard attributes and properties
+will be automatically redirected to correct internal component in template.
+
+## Detailed Explanation
+
+This will be useful when, for example, you have button in template and you want to allow to set attributes directly on it:
+
+```html
+<button orcExposeAsHost>{config.text}</button>
+```
+
+In this case directive `orcExposeAsHost` will make button element as `host` component and attributes from config will be set directly on it.
+
+## Rationale and Alternatives
+
+- Wiring configuration for default attributes manually to components.
+
+## Implementation
+
+Create directive named `orcExposeAsHost` that will take host component and expose it as host component.
+
+Then `RenderItemComponent` will grab it and apply directives and attributes on it instead of real host component.
+
+## Prior Art
+
+None
+
+## Unresolved Questions and Bikeshedding
+
+- It's unclear how to get internal component as host before rendering real host component because all attributes already will be applied by that time
+
+- It requires support from the upstream lib ng-dynamic-component to be able to provide custom ComponentInjector for different directives on dynamic components.
