[Bioperl-l] Phyloxml <alignment> - made-up 'align' xml-language 2

[Christian Zmasek]

I forgot: What the parser should do if it encounters data from other namespaces (or simply unknown (new?) phyloxml elements) is to simply ignore them, without breaking.

Hi, Mira:

I am so sorry for being not more clear in my examples.
The "<align:alignment></align:alignment>" data was intended as an example of how xml data from other namespaces  (in this case "align") could reside inside phyloxml documents.
There is absolutely no need to parse and store these data from other namespaces/xml-languages by your parser/objects.

Christian

PS: To be clear "align", is the name of a _fictional_ xml language which looks like it can store alignments.

Mira -

I've not thought too clearly about how this should go, certainly  
Bio::AlignIO should be reused for the parsing aspect, although I'm  
not clear what format the alignment is in?

At some point this is might need to be unified with the NEXUS-type  
objects that the Bio::NEXUS group has worked on.  We may have to work  
with them to define the proper object here that holds both tree and  
alignment data and allows slicing out either from the object.

So a super-object is probably going to have to be created to marshall  
out the trees and alignment data.  I didn't realize the spec was  
going as far as to encapsulate all of the alignment data as well.  We  
may need to think about whether we can support all of the aspects of  
the spec at this time as well.

I hope other people have input here as well.
