Description Abel Braaksma 2018-12-22 12:25:55 UTC 
The offending line is in 15.3:

"The rules are the same as for an xsl:source-document instruction specifying streamable="yes". If the for-each-source attribute is absent, then the validation and type attributes must both be absent."

I think this is a remnant from the time that for-each-source was only meant for streaming. That is no longer the case.

I suggest we change this to something like:

"The rules are the same as for an xsl:source-document instruction with the same effective value for the streamable attribute. If the for-each-source attribute is absent, then the validation and type attributes must both be absent."

I don't think the headline is correct; there's no implication that validation can only take place if streaming.  But I think we can simply drop the phrase "specifying streamable="yes"", because xsl:source-document validation is exactly the same whether you're streaming or not.

I'm drafting erratum E44, which simply (a) drops the phrase "specifying streamable="yes"", (b) adds a link to §18.1.1 (Validation of Source Documents) (c) says that in 18.1.1 references to attributes of xsl;source-document should be interpreted as references to attributes of xsl:merge.

I see that now too, indeed

It appears to me that (c) is missing from the proposed change. Was that intentional? I think it would add value to specifically say so.
