The DLNA standard actually does support additional subtitle (.srt) files, and is already used by many DNLA media renderers, e.g. Philips HMP5000, Samsung B/C/D TV series, LG TV/player, Panasonic Viera and WD TV HD Live (see profiles.xml from Serviio Media Server and their page on subtitle support for details).
It is specified in the DMR profile by using e.g. <SubtitlesMimeType>text/srt</SubtitlesMimeType>

This is what serviio returns as item within the ContentDirectory: "urn:schemas-upnp-org:service:ContentDirectory:1"

<item id="V_T^INI_65^V_9" parentID="V_T^INI_65" restricted="1">
<dc:title>Arzak Rhapsody 01</dc:title>
<res protocolInfo="http-get:*:video/x-msvideoLNA.ORG_PN=AVI;DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.O RG_FLAGS=01500000000000000000000000000000">*0</res>
<res protocolInfo="http-get:*:image/jpegLNA.ORG_PN=JPEG_TN;DLNA.ORG_OP=00;DLNA.ORG_CI=1;DL NA.ORG_FLAGS=00D00000000000000000000000000000">htt p://</res>
<res protocolInfo="http-get:*:text/srt:*"></res>

As you can see, the URI to the .srt file is given in the media directory and can be read through HTTP.

Now it's just a matter of the Philips TV to actually detect and load the text/srt resource entry and display it like an USB-based srt file.

I realize Philips' limited manpower in adding such functions, but of course I still hope to see this one day in the distant future as firmware update for our TVs.


Update: Technical stuff
One additional note: The reason to assume that the DLNA spec doesn't support external subtitles, is probably, because it's already supported but not mentioned explicitly.
That assumption is wrong, however: One or several external subtitle files can be added like any other additional resource, such as JPEG thumbnails, to the ContentDirectory.

This document on AVTransport mentions this (p.56&58), but even though people from Philips are listed as co-authors, it didn't seem to have spread around the company.

Update: Actually, as the HMP5000 supports external subtitles through DLNA, it _did_ spread around, just not to the TV guys.
Philips, can we expect to see DLNA subs soon? They are part of the standard (see answer above, especially this document: http://www.upnp.org/specs/av/UPnP-av...e-20101231.pdf) and you mark your TV sets as standard compliant. I can't believe you couldn't fully implement the standard you partially made or contributed to.
