7.22.4 Limitations
Any line in XTR XML file cannot be greater than 255 characters.
Comment start tag "<!--" should start on a new line and end tag "-->" should be
last characters on a line.
The XML attributes are case sensitive but the values are not.
XTR cannot be used to playback BIOS bring-ups.
Currently XTR does not support Pacifica platform.
Currently XTR traces recorded off SimNow cannot be played back in other XTR
playback environments.
Although not needed, XTR traces recorded by SimNow might contain data
written by the CPU, e.g. IOW.
