Sounds good. Maybe some "inverted microsoft logic" could be applied: In the past (MS-DOS times) for some parameters an argument staring with '@' meant to read the actual parameters from the file that follows '@' (mostly because the MS-DOS line length was limited to 127 bytes): For XML we should consider everything as a file name, with two exceptions:
1) "-" stands for stdin
2) "@" says the rest is to be taken as file contents (not file name)

So you could have XML that does not start with '<' immediately.
