I’m in process of revising the spec
to address the ID uniqueness issue. In the midst of the edits, I’ve
noticed that the <group> id is an optional attribute. Given that we’re
adding a uniqueness constraint for id, shouldn’t it be a required
attribute? Is it even possible (in the normative context) to impose a
unique constraint on an optional attribute? I think shifting group id to a
required attribute would represent a pretty big change, no?
I’m going to publish a new revision
to the spec momentarily, and in that version I will leave the group id as
optional.
Anyone have thoughts on this issue?
Regards,
Tony

Subject: [xliff] More XLIFF schema
changes
All,
Rodolfo pointed out to me that
<group id>, <trans-unit id> and <bin-unit id> must be unique
within a <file> because they are used to identify the element
“within the file”. More specifically, all the <group id> values
must be unique within <file> with respect to other <group> tags.
All <trans-unit id> and <bin-unit id> values must be unique within
<file> with respect to other <trans-unit> or <bin-unit> tags.
That is, a <group> and a <trans-unit> may have the same id value,
but a <trans-unit> and a <bin-unit> may not have the same id value.
I recommend explicitly stating that
the id attribute must be unique (as stated above) in the specification.
With this understanding, the
constraints for the xid attribute were also possible.
I haven’t added constraints
for the id attribute in inline tags (e.g., g, ph).
I’ve added the constraints to
the XLIFF 1.1 strict and XLIFF 1.2 core & strict schemas, which are
attached.
Attached is a zip with 3 schema
files.
xliff-core-1.2-20060302.xsd
The tool-id attribute was missing
from the elements that should have it (except the ‘tool’ tag).
Constraints were also added,
including group id, trans-unit id, bin-unit id and xid.
xliff-strict-1.1-20060302.xsd
The tool-id attribute was missing
from the elements that should have it (except the ‘tool’ tag).
Constraints were also added,
including group id, trans-unit id, bin-unit id and xid.
Deprecated elements and attributes
are prohibited.
xliff-strict-1.2-20060302.xsd
The tool-id attribute was missing
from the elements that should have it (except the ‘tool’ tag).
Constraints were also added,
including group id, trans-unit id, bin-unit id and xid.
