[reportlab-users] a bit confused on rml present and future

[pier carteri]

Hi to all,
thank you Andy for your reply.
 I agree with you points; just to clarify:
-with enterprise-grade I mean something stable and with good performance.
 This has no relation with cost. If I, (with my mail) give you the
idea that I consider ReportLab
 too expensive, this was not my intention and I apologize for that.
-thank you to point me to the dtd

I'm considering the idea to develop something to create rml file,
so from a legal  point of view the things that I've to point out is thant
Report Markup Language and RML2PDF are trademarks or ReportLab.
That makes perfect sense to me.


Best Regards
Pier
