[PHPTAL] Imploding tal:attributesfrom source array

[Werner]

Hi Anton

Unfortunately this does not seem to work. It seems that there needs to 
be at least one attribute key to be specified before the attribute's 
value will be rendered.

E.g. if you use:
    <img tal:attributes="${imgAttr}" />
You get:
    <img/>

I ony can get something rendered if I specify an attribute name:
    <img tal:attributes="myattrs ${imgAttr}" />
You get:
    <img myattrs=" id some_id; class some_class; src img/beautiful.jpg;"/>

Why is this so hard? One would almost expect tal:attributes to be able 
to handle any assoc array right there in place? E.g.
    <img tal:attributes="${myAssocArray}" />

I guess this is not the intended way, eh? The only alternative seems to 
be to write a very long tal:attributes definition that would cater for 
any possible attribute, but I;m sure there must be a better approach...?

Kind Regards,
Werner
