Hi, 

I ran over an unexpected bahavior of BaseX 9.7.3

Can anyone explain?

Note: BaseX 9.7.3 is running with MIXUPDATES=true

file1.xq: create to functions in a list and call each function with a list comprehension

----

declare function local:bla(){<bla id=""/> }; (local:bla#0,local:blubb#0)!.()

----

Result: as expected

<bla id=""/>
<blubb id=""/>

file2.xq: same as above, but in an xquery:eval

---

xquery:eval( )!.()

---

Result: as expected

<bla id=""/>

<blubb id=""/>

file3.xq: same as file1, but with a little "twist"

---

declare function local:bla(){<bla/> update {insert node attribute id {} into .}}; (local:bla#0,local:blubb#0)!.()

---

Result: as expected 

<bla id=""/>

<blubb id=""/>

file4.xq trying to call the same with xquery:eval will not work ([xquery:update] No updating expression allowed.), so we use xquery:eval-update()

---

xquery:eval-update( )!.()

--

Result: expected

<bla id=""/>
<blubb id=""/>

But the result is: 

local:bla#0
