On our Roxen 4.5 installation, we need to add an .htc behavior file
to unobtrusively add alpha-channel PNG support to Internet Explorer
for embedded images.
..htc files are required to have a MIME-type of text/x-component (as
of Windows XP SP2).
However, we cannot figure out how to configure Roxen so that that a
new Content Type/mime-type shows up in the "Type" select menu in the
"Metadata" area.
BTW, for the curious, here is some more info on HTCs, and then a link
to what we are trying to do.
For Microsoft Internet Explorer 5 and later, HTML Components (HTCs)
provide a mechanism to implement components in script as Dynamic HTML
(DHTML) behaviors. An HTC is an HTML file that contains script and a
set of HTC-specific elements that define the component; it is saved
with an .htc extension
