Attributes on component's root tag

[bradisbell]

It doesn't seem to be possible to add attributes to a custom component's root tag. For example:

<my-tag is="svg" viewbox="0 0 16 9" xmlns="http://www.w3.org/2000/svg">
   ...
</my-tag>

Then when I use the tag:

<svg is="my-tag"></svg>

In the output, the viewbox and xmlns attributes don't appear.

This is particularly problematic in SVG where I'd like to accept height/width attributes. Is this possible?

I can enhance the compiler to match these attributes but for now a quick workaround for it is to set them as expressions:

<my-tag viewbox={'0 0 16 9'} xmlns={'http://www.w3.org/2000/svg'}>
   ...
</my-tag>

Side note: is="svg" doesn't make really sense as attribute
