No, the HD information comes from your EPG data only.  Channels are
not marked as HD capable as they can (in theory) change between HD and
SD transmission at any time.

Yes, that is the correct format.  Here is a random example programme
listing from my current EPG:

<programme channel="tv1.freeviewnz.tv" start="20200327004000 +1300"
stop="20200327011000 +1300">
    <title>Emmerdale</title>
    <desc>Can Kerry talk Amy into running away? Nate makes a
disturbing discovery. Robert prepares for his plea hearing.</desc>
    <episode-num system="dd_progid">10563907</episode-num>
    <video>
        <present>yes</present>
        <quality>HDTV</quality>
    </video>
    <subtitles type="teletext" />
    <rating system="Freeview">
        <value>PGR</value>
    </rating>
</programme>

You can find the definition of the XMLTV format in its DTD file.  In
Ubuntu, that is found here:

/usr/share/xmltv/xmltv.dtd

And there is no point in doing that as you have no way of knowing for
each programme whether it is actually HD or not.  If your EPG does not
provide HDTV information, then you should not be using MythWeb's
option to record HDTV versions of programmes.  It is intended for the
situation where you have access to both HD and SD versions of the same
programme (usually on different channels) and it tells MythTV to
prefer to record the HD version.  But I thought that if an HD version
was not available in the current EPG data, it would select an SD
version to record anyway.  If that is not happening, then maybe you
have found a bug.  I have never used that HD option myself, as our New
Zealand EPG sources have never been reliable about flagging the HD
programmes.  Instead, I have been using the "This channel" schedule
filter to make programmes record from our HD channels instead of the
SD "plus 1" channels.  And I have also set the SD "plus 1" channels to
be of lower priority than the main HD channels, so the HD channels are
preferred.
