csprd 051: Ignorable

Hi Ryan,

Trying to address issue 51:
(answering you email: https://lists.oasis-open.org/archives/xliff-comment/201305/msg00042.html)

The current definition text is:

"Information that needs to be preserved but does not need to be modified/translated."

Would the following text be better:

"Part of the extracted content that is not included in a segment (and therefore not translatable). For example some tools may use
<ignorable> to store the white space and/or codes that are between two segments."

Thanks,
-yves
