Question about ?= syntax #650
Description
Hi there,
In the core-header-panel component, the following syntax is used:
<div id="mainContainer" flex?="{{mode !== 'cover'}}" on-scroll="{{scroll}}">
<content id="mainContent" select="*"></content>
</div>
Is the ?= part of the web component standard or is it polymer specific?
Cheers,
Jun

flex?=is Polymer specific to the best of my knowledge. See https://github.com/Polymer/TemplateBinding/blob/master/tests/tests.js#L928 for our unit tests around the feature.jmatsushita commentedon Jul 21, 2014
Thanks! Hopefully it won't be too much of an obstacle to convince html parser authors (@kangax) to allow for it.
